Answer: 54 degrees
Step-by-step explanation:
Since AZ is tangent to circle V, it forms a 90 degree angle with the circle. If you compare XW with AZ, you can see they are perpendicular to each other. Angle W has already been found, and it's 36 degrees.
So if you subtract 90 by 36, it gives you YWZ, 54 degrees.
