What is the interior angle sum of a 15-gon?

Explanation:

Use the formula below with n = 15

S = 180*(n-2)

S = 180*(15-2) ... replace n with 15

S = 180*13

S = 2340

This formula is based on the idea that a triangle's interior angles add up to 180, and the idea you can partition any polygon into triangles (aka "polygon triangulation")

  720°

Step-by-step explanation:

Use the formula for the Sum of interior angles: I = 180(n - 2) , where n is the number of sides/angles.

I = 180(15 - 2)

 = 180(13)

 = 720

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

answer: i guess 105 degrees?
