Providing that it is a regular 15 sided polygon then each interior angle will be 156 degrees
Exterior angle = 360/16 = 22.5 So interior angle = 180 - 22.5 = 157.5 degrees.
The exterior angle of a 7 sided shape add up to 360 degrees The interior angles of a 7 sided shape add up to 900 degrees
170.27 degrees
Each interior angle of the regular 8 sided octagon measures 135 degrees
If it's a regular 8 sided octagon then each interior angle is 135 degrees and they all add up to 1080 degrees
Each angle in a 28-sided shape is about 167.14 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.
Exterior angle = 14.4 degrees Interior angle = 165.6 degrees
Exterior angle = 360/16 = 22.5 So interior angle = 180 - 22.5 = 157.5 degrees.
The exterior angle of a 7 sided shape add up to 360 degrees The interior angles of a 7 sided shape add up to 900 degrees
The equation to find the size of the interior angle of an n sided shape is (n-2)180/n For a 120 sided shape, you need to plug n=120 into this equation. (120-2)180/120 =118x180/120 =177 Thus a 120 sided shape does have an angle of 177 degrees, and the statement in the question is true.
If it is a regular 12 sided polygon then each interior angle is 150 degrees.
Each interior angle is 162 degrees.
