Question

If angle X has a measure of 40 degrees and angle Y is vertical to angle X what is the measure of angle Y?

Answer 1

Angle y measure would most likely be 20 degrees

Answer 2

If an angle is 70 degrees and there is an angle vertical to it, then that other angle also equals 70 degrees. Therefore, if angle X equals 40 degrees, then angle Y also equals 40 degrees. Hope this helps.
