Question
Lines XY and CD intersect at M. If m∠XMC = 3x + 16 and m∠YMD = 5x - 54, find, in degrees, m∠CMY.

Since XMC and YMD are vertical angles,
3x+16 = 5x-54
Solve for x, and you have their measures.
Now, since CMX and CMY are supplementary, CMX+CMY = 180
3x+16 = 5x-54
Solve for x, and you have their measures.
Now, since CMX and CMY are supplementary, CMX+CMY = 180
