Divide a circle 360 degress by 15 and you'll get the number of sides. This works with any polygon with regular sides.
Vice versa if you want to draw a regular sided polygon if you draw a circle and then the radii using the angles and then join the ends ...
You might also want to draw or create a diagram for future reference of the angles you can divided a circle into?

sum of exterior angle and interior angle of a polygon is always 180. So each internal angle is 180-15= 165. Now sum of angles of a regular polygon is 180(n-2).
so 180(n-2) = 165*n
or 180n - 165n = 360
of n = 360/15
or n = 24

Forumula for Eea=360/n
15=360/n
15n=360
n=24
number of sides =24

if outdoors perspective measures 5 levels, then the corresponding indoors perspective could be 275 levels {360-(5+a hundred and eighty)}. it is impossible for a polygon to have an outdoors perspective of 5 levels

sum of exerior angles is 360°, so 360/15 = 24 sides.
