Question

What is the measure of B, in degrees?

A. 160
B. Cannot be determined
C. 74°
D. 329

Answer 1

D. 32°

Explanation:

C=A because the triangle is isosceles.

A+B+C=180- Sum of angles in a triangle

74+B+74 = 180

148+B=180

B=32°

Answer 2

32°

Explanation:

The triangle ABC is a isosceles so angle A = angle C

The sum of interior angles in a triangle is = 180°

74 + 74 + angle B = 180

B = 32°
