19.!work out the sum of the interior angles for a 40 sided polygon.⁰ (2) 20.!the sum of the interior angles in a polygon is 7380⁰.!calculate the number of sides the polygon has. For n=8, the figure is: Each corner has several angles. The angle next to an interior angle, formed by extending the side of the polygon, is the exterior angle.
