Answer:

angle C = 69 degrees

Step-by-step explanation:

(6x - 9) + (6x - 24) + (81 - x) = 180

11x + 48 = 180

11x = 132

x = 12

(81 - 12) = 69 degrees

Answer:

69°

Step-by-step explanation:

All angles in a triangle must add to 180°:

(5x+9)+(4x+15)+(x+36)=180

10x+60=180

10x=120

x=12°

The problem asks for the measure of angle C:

C=(81-x)°=69°

You were on the right track because you got the value of x correct. You just didn't answer the problem correctly.
