Each interior angle measures 160 degrees
360/number of sides = exterior angle
Each exterior angle is 72 degrees
Each exterior angle measures 15 degrees

The exterior angles add up to 360 degrees.
Each interior angle measures 160 degrees
360/number of sides = exterior angle
You simply do 360/20=18 so the size of each interior angle is 18 degrees.
Providing that it is a regular 12 sided polygon then each exterior angle measures 30 degrees
Each exterior angle measures 36 degrees
Each exterior angle is 72 degrees
Each exterior angle measures 15 degrees
If its a regular 9 sided polygon then the exterior angles are 40 degrees.
18 degrees
The exterior angle of a 18 sided shape is 360/18 =20 degrees The exterior angle is always 360 divided by the numbe of sides of that polygon. =) what the hell im i doing answering this?
