What is the measure of B, in degrees?
A. 160
B. Cannot be determined
C. 74°
D. 329

Answer:
32°
Step-by-step 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°
Answer:
D. 32°
Step-by-step 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°
