Explanation
According to the current diagram, y° is larger than x°. But remember, the figures are not always drawn to scale and you are free to make changes provided you keep the information given as a constant. In this case, the constant is that PS = SR.
So keeping line PR the same, where PS = SR, move Q around to see what happens to x and y:
As you can see, it’s impossible to determine which angle is greater without having more information about point Q.
Hence option D is correct.

The easiest way to solve this problem is to attempt to produce two different answers. What if we imagined that point Q was stretched waaaay off to the right? Draw a quick picture. This would make y quite large and z quite small.
Now how can we make z large and y small? If you imagine smushing point Q down very close to the base, then z would be quite large while y would be small. So the answer is D.
