The sum of the measures of the interior angles of an n-gon is: 180(n - 2) A regular n-gon has all congruent angle measures, so after you use the formula above with n = 15, divide the sum by 15 to find the measure of each angle.
OpenStudy (vickyisthesmartone123):
it is 120 trust me I am quite smart according to people
OpenStudy (mathstudent55):
@Vickyisthesmartone123 Other than being incorrect, your answer of 120 is great because it may be correct for another problem we are not solving now.
OpenStudy (anonymous):
it would be B 156 then
OpenStudy (mathstudent55):
Correct
