Question 1020518: The expression (n+3) represents the measure of an exterior angle of a regular 18-gon. What is the value of n in the expression? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! All the exterior angles add to 360 degrees
Therefore, each exterior angle is 20 degrees in an 18-gon.
n+3=20
n=17 degrees
