The answer is A
Explanation:
Since it a parallelogram angle P and R have the same value. Since the parallelogram is split into 2 triangles all you have to do is find one triangle then you can find the values on the other. The way you do this is since a triangle is 180 degrees you have to subtract 75+60 from 180 which will give you the last angle you need which is 45. Then you plug in the rest on the other side.
