If the interior angles of a polygon add up to 1980 degrees then it has 13 sides
The sum of interior angles: (13-2)*180 = 1980 degrees
The sum of the exterior angles cannot be 1980 degrees - it is always 360 degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1980 degrees.
The interior angles add up to 1980 degrees.

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.
If the interior angles of a polygon add up to 1980 degrees then it has 13 sides
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.
If the sum of its interior angles is 22*90 which is 1980 degrees then it will have 13 sides Consider the following rules that are applicable to all polygons:- (interior angles+360) divided by 180 = number of sides (number of sides -2) multiplied by 180 = sum of interior angles The above question is rather confusing because it implies that the interior angles of the polygon is the equivalent of twenty two right angles which is the same as 1980 degrees but working out how many sides the polygon has then the same rules apply. (1980+360)/180 = 13 sides (13 -2)*180 = 1980 degrees
The sum of interior angles: (13-2)*180 = 1980 degrees
The sum of the exterior angles cannot be 1980 degrees - it is always 360 degrees.
