Best Answer

They all add up to 360 degrees.

If the polygon is a 'regular' one, then each exterior angle is 360/number of sides .

1260 degrees

The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.

If the polygon (not ploygon!) has n vertices, the sum of the angles is (n-2)*pi radians or (n-2)*180 degrees.

The exterior angles of any polygon add up to 360. 360/15 = 24

The exterior angles of any polygon add up to 360. 360/15 = 24

The sum of the exterior angles of a polygon is 360°. There are the same number of exterior angles as there are sides. For a regular polygon all the angles are the same size: → number_of_sides × exterior_angle = 360° → exterior_angle = 360° ÷ number_of_sides → exterior_angle = 360° ÷ 5 = 72°

Exterior angles are supplementary with interior angles, so 180-30=150

they are angles that are usually parallel and that crossed the line that are oppsite from each other
