OpenStudy (beastboy17):
let me know if it works
OpenStudy (anonymous):
i need help on how to do it though
OpenStudy (beastboy17):
ok hold up whats the question
OpenStudy (anonymous):
If y=22, find M<C.

is it a multiple choice or you have to write it ?
OpenStudy (anonymous):
A.44
B.68
C.136
D.60

btw
OpenStudy (anonymous):
44???
OpenStudy (mle):
angle A = 22 + 22 = 44
then to find Angle C
180 - 44 = 2*(m<C) solve
OpenStudy (mle):
please ask in the mathematics section next time
OpenStudy (beastboy17):
thanks for the help mLe

i am still confused can you do it step by step
OpenStudy (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?
OpenStudy (anonymous):
ok yeah thanks
OpenStudy (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
OpenStudy (mle):
2 C = 180 - 44

i get 272 though
OpenStudy (mle):
divide 2 from both sides to cancel a multiplied 2
OpenStudy (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
OpenStudy (anonymous):
\[2\times44=180-44???\]
OpenStudy (anonymous):
or \[2x=180-44\]

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