Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
Exterior angle = 14.4 degrees Interior angle = 165.6 degrees
If it's regular then 360/20 = 18 degrees
There's no such shape because a pentagon has only 5 sides. If you meant a regular 100 sided polygon then the answers are:- Exterior angle: 3.6 degrees Interior angle: 176.4 degrees
A nine sided shape that is called a regular nonagon.
Any shape can have an exterior angle of 45 degrees. If you are talking about exterior angle sum, it is always 360 degrees for any polygon. If you are talking about a regular polygon (equal exterior angles), it would be 360/45=8 sides. Therefore, a regular octagon has exterior angles of 45 degrees.

Exterior angle = 14.4 degrees Interior angle = 165.6 degrees
It is a regular 10 sided decagon
If the exterior angle is 30o then the shape has 360/30 = 12 sides. An interior angle = 180 - exterior angle = 180 - 30 = 150. Since the shape has 12 sides the interior angles sum to 150 x 12 = 1800o.
If it's regular then 360/20 = 18 degrees

A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
A nine sided shape that is called a regular nonagon.
The sum of all exterior angles of a polygon is 360 degrees. In a regular polygon, all of the exterior angle are equal, so there must be 360/72=5 sides of the polygon, which makes it a pentagon.
