A 13 sided polygon interior angles add up to 1980 degrees
It will have (1980+360)/180 = 13 sides
It will have (1980+360)/180 = 13 sides
A 1980 sided polygon makes 1980 vertices.
The formula for the sum of the angles of an interior polygon is 180(n-2), where n is the number of sides, so then you solve 180(n-2) = 1980. (n-2) = 11 n = 13. So the polygon has 13 sides.
A 13 sided polygon interior angles add up to 1980 degrees
If the interior angles of a polygon add up to 1980 degrees then it has 13 sides
