Question

lmnp is a rectangle. given that the measure of ∠pql = 50°, which expression below could be used to find the measure of ∠mqp?
90 - 50
90 + (50 - 10)

Explanation:

Step1: Recall angle - sum property in a rectangle

In rectangle LMNP, ∠MQP and ∠PQL form a right - angle (since each angle of a rectangle is 90°).

Step2: Find the measure of ∠MQP

If ∠PQL = 50° and ∠MQP+∠PQL = 90°, then ∠MQP=90 - 50.

Answer:

90 - 50
