Answer:
Angle PRQ is 15 degrees.
Explanation:
This is because the sides PQ and RQ are sides of a shape with 12 SIDES. So all you have to do is find the degree measurement of each angle of that shape, which is 150 degrees. And since they decided to create another line (PR). It makes it a triangle. Since the triangle is isosceles automatically, then just subtract 180-150=30. Then divide by 2, giving you 15 your answer. This represents each of the acute angles which are equal since the triangle is isosceles.
