Pick a point around the center of the polygon. Join each vertex to this point. You will now have 10 triangles. The total angle of these 10 triangles is 10x180 degrees. Now you need to subtract the angles of the ten triangles at the center (which is 360 degrees). Therefore total internal angles is (10x180)-360 = 1800-360 which is 1440 degrees. A 10 sided polygon has 20 internal angles. So each angle would be 1440/20 = 144/2 = 72 degrees
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
interior angle of an n-sided polygon = (180(n-2)/n)°interior angle of a 24-sided polygon = (180x22/24)° = 165°
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
Providing thar it is a regular 15 sided polygon then each interior angle will be 156 degrees
the interior angle of a 7 sided regular polygon is 128.57 degrees
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
interior angle of an n-sided polygon = (180(n-2)/n)°interior angle of a 24-sided polygon = (180x22/24)° = 165°
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
The interior angle of a regular polygon with x sides is 180(x-2)/x. As a result, each angle of a regular 50-sided polygon is 172.8.
Providing that it is a regular 7 sided polygon then each interior angle is 900/7 degrees
If it is a regular 12 sided polygon then each interior angle is 150 degrees.
Providing that it is a regular 38 sided polygon then each interior angle will measure: 170o31'34.74''
Providing thar it is a regular 15 sided polygon then each interior angle will be 156 degrees
the interior angle of a 7 sided regular polygon is 128.57 degrees
