ANSWER


x = 11

Step-by-step explanation

According to the exterior angle theorem, the sum of remote interior angles equal an exterior angle.

This implies that,


(7x + 7) \degree + 66 \degree =(1 2x + 18) \degree

We group the similar terms to get:


7 + 66 - 18 = 12x - 7x


55= 5x

Divide both sides by 5.


x = (55)/(5)


x = 11
