Question

Find the measure of each interior angle of a regular polygon 18-gon.

Answer 1

160

Explanation:

finding the sum of all interior angles of the polygon:-

n is no of sides

=(n-2)*180= (18–2)*180=16*180=2880 degree.

One angle formula= sum/no of sides

Sum of all eighteen angles=2880,

One angle=2880/18=160 degree.
