15 sides
The interior angles of a 15 sided polygon add up to 2340 degrees and if it is a regular polygon then each interior angle is 156 degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. (180 x 13)/15 = 156 degrees

If its interior angle measures 156 degrees then it will have 15 sides
If each interior angle measures 156 degrees then it must have 15 sides
15 sides
It will have 15 sides
156 = [180(n - 2)]/n = 156n = 180n - 360 ie 24n = 360 so n = 15
If it's a regular polygon with each interior angle being 156 degrees then it will have 15 sides
If the interior angle measures 156 degrees, this means that the exterior angle is equal to 180 - 156 = 24 degrees. Dividing this by the full 360 degrees of a circle, gives 360/24 = 15. The polygon therefore has fifteen sides. A fifteen-sided polygon is called a pentadecagon or pentakaidecagon.
15 sides.
Interior angle = 156 degrees so exterior angle = 180 - 156 = 24 degrees. Then number of sides = 360 / 24 = 15.
15 sides
The interior angle is the angle formed from two sides of a nth-sided polygon. Because the polygon is regular, all angles formed from any two sides of the polygon are equal. It can be proven, but I won't attempt to, that to find the amount of sides, you use 180-[interior angle], and divide the answer by 360. In this case, 180-156=24, 360/24= 15, thus the polygon has 15 sides. One way to prove it is to imagine the polygon and divide it into isosceles triangles. But I won't go there.
