Question

In the triangle below, what is the measure of angle R?

Answer 1

C. 30 degrees because it mirrors the angle of P.

Answer 2

Option C is correct.

Explanation:

Given:

PQ = 8 , QR = 8

m∠P = 30°

To find: m∠R

Since two sides of the triangle are equal.

We have Isosceles triangle.

PQ = QR

⇒ ∠R = ∠P ( angles opposite to equal sides are equal )

So, ∠R = 30°

Therefore, Option C is correct.
