Answer:

I don't know what I'm suppose to solve, but it's probably one of these.

x = 8

Angle A = 48 degrees, Angle B = 132 degrees

Explanation:

(4x + 12) + (15x - 3) = 180

19x +9 = 180

19x = 171

x = 9

Angle A: 4x + 12 --> 4(9) + 12 --> 36 + 12 --> 48

Angle B: 15x - 3 --> 15(9) - 3 --> 135 - 3 --> 132

48 + 132 = 180
