G 4 L 7 Solve Problems with Angles W 13

great for my dear students okay and for be the morning everyone for you guys at the beginning would like to thank all the students yesterday and sent to me by whatsapp thank you for all green thank you okay I'll listen today what 911 you can see the screen with angles please okay 45 45 okay okay here have this problem grow and entity draw 90 degree angle okay as you see it's 90 degree angle and it's divided into two angles one of them with me to certify need to find the another one how to find the another one okay so now have this angle Bart one with major 90 degrees 90 degrees DS square corner like this it's called 90 degrees writing okay and then form it two angles one is with 35 degrees and other one unknown how to find the missing angle here have two mediums the large one the guard angle is 90 and the small one 35 okay so to find the missing one here have for example if this is and so angle or degree plus 35 degree should be equal 90 degree then listen gangly +35 degree should be 90 degrees okay so to find the missing one or the missing angle the noon angry you can do what you can subtract so to find the missing angle it will be 90 - - what yes - 35 so the answer will be yes by so the missing angle is 55° again here have lot of line again with 90 degrees we do with this right angle this angle divided into two angles one of them was measured 35 and the other one don't know what it's widget okay here to find other angle the measure of the other angle is called new angle of missing gangee okay you have to subtract the large angle 90 - they gave an angry the small 135 to find the missing and okay okay now Miss ego was the second page page number 912 the guided practice here you find okay the find angle to confine angry squad combined anger is 90 okay meter is 90 degrees and have here one of the Angus was miserable 75 want to find the other one let's start to solve Swan here have find angle means this Angus the large one okay with me tonight and have given 175 find new find so the total of these of the two angles should be 90 plus 75 should be nine so to find the missing one there's only one way to find it is subtract would subtract here the given angle the large one which is 90 degrees minus - what given 175 the answer will be what 90 minus 75 could be 15 degree so equals 50 okay same way can't do it with number two had here the combined anger is 100 said two combined enemies the large angry okay for two angles one of them is certified the another one is degree fine decay okay so should be plus 35 equal 130 so have to subtract 130 minus certified to find fine okay so have to write here 135 actually 130 minus - what 130 the combined angry the guard one month this part from the ending part of the angle of the large one is 35 so 130 minus 35 equals well yet equals 95 because what 95 here's number three give us find the combined angle the combined one yet have this angle contains of two angles one was neutered 25 and the other one with meter certified here to find the combined angry with you the two angles or the combined angry have to add so have to add 25 plus 35 find find angle equals 160 degrees so the answer should be 60 degree okay okay now all of you guys need all of you great for okay doctor Saab just listen to me okay it's much better for us again plus 35 should be equals what should be equals to 130 so have to subtract 130 135 anyone has question just raise your hand okay will not unmute all only obey you or is his hand you you handed in my head and that garages mhmm it starts Mohammed okay hey give me the combined angry means the large 190 okay and and ask you to find know this small angry have the combined and it contains of two angles small one this end and the other 175 so the total was in and seventy five should be 90 so have to find the missing one AB subtract but it asks you to find the combined angle same number three the two and the large angle means the find angle okay had to add them together means okay anyway if we had the two measures the middle two angles just add them if you have the middle of one engine just subtract from the given end okay Mohammed okay okay Aziza Mohammadi welcome Aziz yes AB resist okay teacher how do know same question was Mohammed okay okay here said if you have one angle and the other one unknown or new language means that have to subtract subtract the given angle from 90 from the combined angle have given you the combined and asked you to find the unknown angle here gives you the two angles together to find the combined have to add okay Sego was next one or the next page page nine hundred and you you you number four five six and seven say find each unknown being the meeting angry number four have the combined anger with measured 50 degrees the combined angered the Lord angle means the large angle whose measure 50 degrees this Angwin okay with 50 degrees divided into two angles one angry with meteor 13 and other one noon with us as liter so how to find this one okay maybe someone he can answer it okay someone his hand no one harm didn't maybe the game you can answer it Muhammad subtract yeah it's truck what Muhammad what should write what minus 180 minus 50 no she start by the Lord 1 by the Lord 150 yes 50 - kitchen thank you ok okay as your friend Muhammad and my wit form for be okay as he answered why number four here had to combined one with Musial fifty and given us 30 and an moon is so to find to subtract the combined angle fifty minus the given 130 to beat one okay mission share for and they never takes yet this mission what have any question know know that okay Michelle okay number five 90-70 yes excellent 90 degrees minus 70 because the what which are 22 mountain thank you here next one have Chevy net z7n went mutant yes yeah you can also number six yeah crazy yet answer number six please 25 equals 50 yeah it's excellent ittsan thank you another one can answer that raise your hand if you want to answer okay just raise your hand if you want to answer okay let me choose one there is no one resistant save for nicer and nicer from 4b good morning again okay okay let me choose another one okay will be back to you no sir can you please cancel number seven okay guys you understand four five and six to find unknown and we just subtract the combined angle minus the given angle here have have to find the combined angle that's fine to combine angry give us here the combined and okay what what what the large angry he'll give us one hundred things okay this is not what the middle of the with the square corner angle which has squirt corner but it Smigiel okay let me take my hammer in my Eric is how much you know the answer Hammad you okay 50 yeah - yes no 125 here okay will accept let it guys thank you Muhammad here have this the pint angle was measure what 150 right so here 150 means this all of this angry see the large with this one this 150 this combined angle contains of two angles one with little you need to find it and the other on given someone asked there is no any number but here we know you for any anger with square corner like this called 90 degree it is called this right angle is measured 90 degrees so this one is already 90 degrees haven't so now to find to find the unknown angle or the missing angle have to subtract 150 minus 9 will be required 60 degree okay is it clear for all again you guys all of these all these unless you give us the combined engine combined angin is the large one the large one given combined angle here 50 cloud 150 this contains of two angles 30 and what should subtract 50 the combined 1-30 the bart angle of the combined angle 30 the 50 minus 30 equals 20 same way this one have the combined angle which is me with middle 90 degrees okay so have to subtract 90 minus 70 will give us the same here have 125 combined angry this 125 just subtracted 125 minus 75 the given angle to give us the missing angle in which is degrees so equals 125 minus 17 equals 50 here have with the combined angle is media 150 degrees it's contains of two angles one with right corner or square corner it's called the right angle the right angle has measure of 90 degrees and this one unknown so to find the unknown angle okay which is have to subtract 150 the combined angle minus minus 90 degrees the given one so 150 minus 90 equals 260 okay any more question about this if you have any question please raise your hand if you have any question please raise your hand okay okay now may have it okay Hamid yes yes yeah yes okay okay the same like this problems should be the homework okay now let's go with number eight and nine you can do it by yourself tool by using your protractor draw triangle with one right angle draw triangle with right and we have we will skip this one okay we'll skip this don't solve it skip it okay you guys let's skip this one okay now we are going for the next page at number 11 skip number 10 also will solve living in 12 okay someone has question okay okay guys here in number 11 the question is the combined measure all the angles is fixed 150 degrees okay okay fat first please you have question fat yes SPS from one ok here in number 11 the combined the measure of angles is 150 150 degrees this one you 150 degrees okay so one angle measure fifty degrees which one this one son measured measured by fifty degrees find the value of this one okay so have to do what had to add or subtract to give us the combined angle large one contains of two animals one with mere fifty and the other one is to find this but we should do who can answer it you someone raised his hand yes at the answer you said yes fell you need answered okay I'll take Mohammed David Mohammed new dancer 150 150 minus 15 equals what 100 Nixon okay okay now in number 12 okay find the value of explain how you solve with this problem okay how to find the here given us this is right angle right this is right anger this is right angle okay okay the tens of two Emmys one of them scale and other one two times is 2 so have 2 2 times and the other one it will be so have here how many have to pay and could be 3 so can do like this to 2 times means okay plus - it was worth because what the right angle means me here 90 degrees so now have okay plus means live to apples plus one Apple to apples and one upper will be worth three apples like this two pencils and one pencil will be three pencils like this you can add letters okay so have to equals 90 degrees okay pre-k means three times by what equals 90 degrees so have it right you like this 3k means three times by 3 times 3 1 and now what inverse operation of finds solve this equation so right here pay equals what but it's 90 divided by 3 equal to 30 or three times by what it was ninety three times good so the answer here should be thirty degrees okay okay we finish our listen we have the homework for today is SPS homework the homework for today today's homework as SPS homo the school of like okay Chronicle mark and the school website okay we are finished now hope you understand the lesson please wha-hey new account on SBS and solve the homework to be the same in the book bade 915 and the 916 have good day all of you see you soon inshallah good boy
