Triangle ABC has the following angle measures:

m∠A = (x + 6)°, m∠B = (3x − 15)°, m∠C = (5x + 36)°

What is m∠C?

17°
23°
36°
121°

Answer 1

121

Explanation:

Answer 2

121°

Explanation:

x + 6 + 3x -15 + 5x + 36 = 180

9x + 27= 180

9x = 180 - 27

9x = 153

9/9 x = 153/9

x = 17

mC = 5·17 + 36

85 + 36
