mB = 34°

What is mA?

B. 56°
C. 73°

Answer 1

C!

Explanation:

Answer 2

C. 73

Explanation:

angles A and C will be the same because their sides are the same length!

so to solve this, let's set up an equation

• 34 + 2x = 180
• let x represent the missing angle

now let's solve!

• 2x = 146
• x = 73

angle A = 73
