Answer:

C = 132

Explanation:

The measure of the exterior angle of a triangle is equal to the sum of the opposite interior angles

20x+12 = 9x+13x

Combine like terms

20x+12 = 22x

Subtract 20x from each side

20x-20x+12 = 22x-20x

12 = 2x

Divide by 2

12/2 = 2x/2

6 =x

QRX = 20x+12

20*6 +12

120+12

132
