Answer:

Correct answer:  m∠A = 52°

Step-by-step explanation:

Given:

m∠A = 9 x - 2 = ?

m∠B = 16 x

m∠C = 5 x + 2

The sum of the inner angles in a triangle is 180 degrees

m∠A + m∠B + m∠C = 180°

9 x - 2 + 16 x + 5 x + 2 = 180

30 · x = 180

x = 180 / 30 = 6°

x =6°

m∠A = 9 x - 2 = 9 · 6 - 2 = 54 - 2 = 52°

m∠A = 52°

God is with you!!!
