Question

Triangle P Q R is an isosceles triangle with PQ = PR if R =42 .Find the measure of p​

Answer 1

Answer:

p is also =to 42

Step-by-step explanation:

because of isosceles triangle pls mark me as brainly

Answer 2

Answer:

Angle P = 96 degree

Step-by-step explanation:

In triangle PQR,

PQ=PR

Therefore,

Angle Q = Angle R (Theorem 7.2)

So, Angle Q = 42

Angle P + Angle Q + Angle R = 180 (Angle Sum Property)

Therefore,

Angle P + 42 + 42 = 180

Angle P + 84 = 180

Angle P = 180 - 84

Angle P = 96

Hence, found
