Each interior angle of a regular 24 sided polygon is 165 degrees

If it is a regular 8 sided octagon then each interior angle is 135 degrees

Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape

Each interior angle of a regular 9 sided shape measures 140 degrees

Exterior angle = 14.4 degrees Interior angle = 165.6 degrees

Providing that it is a regular 15 sided polygon then each interior angle will be 156 degrees

The equation for the size of an interior angle of an n-sided regular polygon is (n-2)180/n. When n=7, the interior angle of a regular sided shape would be 5x180/7 or approximately 128.57. The polygon in the question has an interior right angle (90 degree angle) and thus cannot be a regular shape. A 7 sided shape is called a heptagon. Thus, the shape described in the question is an irregular heptagon.

the answer is 2340 deg. in general for an "n" sided figure, the internal angle is (n-2)*180

Exterior angle = 14.4 degrees Interior angle = 165.6 degrees

The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.

Exterior angle = 360/16 = 22.5 So interior angle = 180 - 22.5 = 157.5 degrees.
