Given that ABC XYZ, mA = 40, and mC = 55, find mY.

Answer 1

It's not clear whether ABC are angles or XYZ are angles. If you are thinking of similar triangles, then

mY = mB

Since A+B+C = 180
40+B+55 = 180
B=85

Therefore, mY is also 85

Answer 2

Given that ABC XYZ, mA = 40, and mC = 55, find mY.

Answer 3

85

Answer 4

Given that ABC xyz,m a=40 and m c =55 find m y
