exterior angles add up to 3600.
360 divided by 23 = 15.65 (2dp)
180-15.65 = 164.350

The sum of the exterior angles of any polygon is 360 degrees
It is: (23-2)*180 = 3780 degrees
The formula for the sum of the interior angles of a polygon is: 180 * (n - 2) where n is the number of sides of the polygon. So the sum of the angles of a polygon with 25 sides is 180 * 23 = 4,140.
The sum of the angles of a polygon is equal to 180° times (n-2) where n is the number of sides.For a 23-sided polygon, that would give a total of (180°) x (21) = 3780°. If the angles are all the same, each would be 3780° ÷ 23 = 164.3478°
