Question

OA) 30°
O B) 60°
D) 50°
OC) 90°

Answer 1

Answer:

A

Step-by-step explanation:

We know that the sum of interior angles in a triangle is 180°. Looking at ΔWYZ, we can write:

? + 75 + 75 = 180

? + 150 = 180

? = 30°

Answer 2

The three inside angles of a triangle need to equal 180 degrees.

You are given the bottom two angles.

75 + 75 = 150

WYZ = 180 - 150 = 30

The answer is 30 degrees.
