Question

*Find the measure of an interior angle of a regular polygon with 15 sides. Round to the nearest tenth if necessary.*

Answer 1

Step-by-step explanation:

Finding a regular polygon with x amount of sides, you use the equation $(x-2)$ to find the amount of triangles. Replace x with 15 and you will get 13. Each triangle has angles that add to $180^{o}$, so you would do 180 * 13 to find the total of all of the interior angles, = 2340. Then, divide 2340 by 15, and you will get 156!
