(n-2)(180) use that formula to find the sum of the interior angles of a polygon in degree
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
If one interior angle is 165 degrees, find the number of sides of the polygon.
the formula for an n-sided polygon to find it's interior angle is (n-2)180/n so the answer is 156 degree's.

The interior angle of a polygon in degrees is 180*(n-2)/n, where n is the number of sides of the polygon. In radians, it is pi*(n-2)/n.
AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon
Subtract the interior angle from 180
To find the sum of the interior angles and the sum of the exterior angles of any polygon. To review linear measurement to the nearest sixteenth of an inch and angle measurement to the nearest degree. To construct a polygon and its exterior angles given the number of sides. hope this helped
remember this formula for the number of sides = n sum of internal angles of a regular polygon = [2x(n-2)x90 degree] each interior angle of a regular polygon = [2x(n-2)x90 degree]/n each exterior angle of a regular polygon = 360 degree/n for your question: each exterior angle of a 15 sided regular polygon = 360 degree/15 = 24 degree
Each interior angle: 140 degrees Each exterior angle: 40 degrees
