Answer:

15

Step-by-step explanation:

Exterior angles are always the sum of two angles in the triangle, so let's make an equation!!

3x + 8x - 8 = 157

Add like terms-- 3x + 8x = 11x

Now, the equation is 11x -8 = 157

Now solve for x.

Add 8 on both sides,,

11x = 165

Now divide 11 on both sides to cancel it out and isolate x.

x=15

Hope this helps!!
