exterior angle of the convex octagon

Question

if the exterior angle of the convex octagon are x+15, 2x-3, 3x+6,2x=6, 3x-18,-3x-3,3x-8, & 5x calculate the largest of the eight angles

Answer 1

The exterior angles must add up to 360 degrees. I think you would simply add up all those expressions, simplify, and set equal to 360. Then solve for x.
