Best Answer

The sum of the external angles of any regular polygon is equal to 360. Therefore, a single exterior angle of an icosagon is 360/20 = 18 degrees.

If it is a regular polygon then each exterior angle is 360/20 = 18 degrees

It has 360/20 = 18 sides

360/18 = 20 sides

360/18 =20

360/20 = 18 degrees.

360/20 = 18 sides

360/20 ie 18 degrees, assuming regularity.

If those are exterior angles, the exterior angles of any polygon add up to 360. That would be 20 sides.

If it is a regular polygon then each exterior angle is 360/20 = 18 degrees

each angle= 20 degree

It has 360/20 = 18 sides

The sum of the exterior angles of any polygon and the extension of its adjacent side is 360 degrees.If the 20 sided polygon is regular, then each angle is equal so that each one is 360/20 = 18 degrees.
