Answer:

x = 8°

Explanation:

We know that sum of interior angles of a triangle is 180°, therefore;

(Angle 1) + (Angle 2) + (Angle 3) = 180°

(60)° + (60)° + (-12 + 9x)° = 180°

120° + (-12 + 9x) = 180°

108° + 9x° = 180°

9x = 180 - 108

9x = 72°

x = 72/9

x = 8°

Therefore the value of x is 8°.

Hope this helps!
