Answer:
60 degrees
Step-by-step explanation:
We are given the measures of WY and XY. Using them, we can find out 2WY=XY.
In 30-60-90 right triangle, the hypotenuse is 2 times the shortest leg. This means that this triangle is a 30-60-90 triangle. Angle Y is the angle made by the shorter leg and the hypotenuse therefore it is 60 degrees.
