ok I got a website I use that might help brb

4. anonymous

ok

5. BeastBoy17

https://mathway.com/ this may help

6. anonymous

ok thanks

7. BeastBoy17

let me know if it works

8. anonymous

i need help on how to do it though

9. BeastBoy17

ok hold up whats the question

10. anonymous

If y=22, find M<C.

11. BeastBoy17

is it a multiple choice or you have to write it ?

12. anonymous

A.44 B.68 C.136 D.60

13. BeastBoy17

I have someone who could help u understand better

@ganeshie8

15. BeastBoy17

which do you think could be the answer

16. BeastBoy17

btw

17. anonymous

44???

18. mLe

angle A = 22 + 22 = 44 then to find Angle C 180 - 44 = 2*(m<C) solve

19. mLe

20. BeastBoy17

thanks for the help mLe

21. anonymous

i am still confused can you do it step by step

22. mLe

properties of an isosceles triangle the two angles at the top are equal to each other angle A = y + ? = y + y = 22 + 22 get that?

23. anonymous

ok yeah thanks

24. mLe

then angles B and C are also equal to each other because it is an isosceles triangle A + B + C = 180 (because it is a triangle) B = C so A + C + C = 180 2C = 180 - A A = (22+22) as we found out before

25. mLe

2 C = 180 - 44

26. anonymous

i get 272 though

27. mLe

divide 2 from both sides to cancel a multiplied 2

28. mLe

if you have something you want to move, to the opposite of what it is currently doing 2 C is currently multiplying to move it, we should divide

29. anonymous

$2\times44=180-44???$

30. anonymous

or $2x=180-44$

31. mLe

we are looking for C only A = 44 2 x C = 180 - 44 C = (180 - 44) / 2 yes

32. anonymous

so 2x=180-44

33. mLe

yes

34. anonymous

c=68??

thanks
