Question

Solve for x. Hint: set up an equation for your exterior angle, then use multi-step equation steps to solve for x. A. 2.2B. 4.3C. 17D. 20

Answer 1

In this problem, we have that

5x+(2x+6)=8x-11 -----> by Exterior Angle Theorem

so

Solve for x

Combine like terms left side

7x+6=8x-11

Group terms

8x-7x=6+11

x=17

therefore

the answer is option C
