Hello and Welcome to OpenStudy! :) the equation is probably 180(n-2)/n = degrees of one angle when n = number of sides
OpenStudy (sleepyhead314):
so plug in n = 18 -> 180(18-2)/18 = ?
OpenStudy (anonymous):
pThe formula is: Sum of Interior Angles=180(Number of Angles-2) So you put 18 in for n, and get 2880 for the total sum of the angles. To find the measure of each individual angle, divide that number by 18. Each interior angle measures 160 degrees.
