Answer:

m∠A = 150°

m∠R = 15°

Step-by-step explanation:

ΔPAR is isosceles => ∠P = ∠R => ∠R = 15°

∠A = 180° - 2×15° = 180° - 30° = 150°

Step-by-step explanation: an isosceles triangle has two congruent sides and angles. So if angle p is the non congruent angle, the equation will be 2x+15 = 180°

2x=180-15

2x =165°

X =165/2

X= 82.5

X is the measurements of angle A and R

If P is a congruent angle,then the equation will be 2(15)+X=180°

30+X=180

X=180-30

X=150

So measure of either Angle A or Angle R will be 150, while the other will be 15.
