Answer 2

Answer: x = 11

===============================================

Work Shown:

The angles marked all form a straight 180 degree angle

So they add up to 180. Use this fact to solve for x

-------

(angle AFB)+(angle BFC)+(angle CFD) = 180

(4x+5)+(6x+3)+(5x+7) = 180

15x+15 = 180

15x = 180-15

15x = 165

x = 165/15

x = 11
