The measure of angle Q is 70 degrees. Find the measure of angle P.

Answer:
∠ P = 40°
Step-by-step explanation:
Since PQ = PR then the triangle is isosceles and the base angles are congruent, then
∠ R = ∠ Q = 70° , so
∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°
∠ P = 180° - 140° = 40°
