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

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

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

85

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

To find mY, we need to use the fact that corresponding angles of congruent triangles are equal. In this case, since ABC is congruent to XYZ, the corresponding angles are equal.

We know that mA = 40 and mC = 55. Therefore, we can conclude that mY is also 55 since it corresponds to angle C in XYZ.

Therefore, mY = 55.
