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.
160
360/20 = 18 sides
360/20 ie 18 degrees, assuming regularity.
If it is a regular polygon then each exterior angle is 360/20 = 18 degrees
If those are exterior angles, the exterior angles of any polygon add up to 360. That would be 20 sides.
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.

Each exterior angle measures 20 degrees Each interior angle measures 160 degrees
360/18 = 20 sides
