Answer 1

Answer: ∠R = 137°

Step-by-step explanation:

The opposite angles of a quadrilateral are supplementary (equal to 180°).

Since ∠P and ∠R are opposite angles, their sum is 180°

∠P + ∠R = 180°

y + 3y + 8 = 180

4y + 8 = 180

4y = 172

y = 43

∠R = 3y + 8

     = 3(43) + 8

     = 129 + 8

     = 137
