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
A hexagon IS a six sided polygon. A REGULAR hexagon is the shape we tend to think of when we say hexagon because it has equal sides and equal internal angles. However, a hexagon can have unequal sides and internal angles and still be a hexagon. A hexagon is just a shape with six sides.
The formula to find the sum of the angles of a polygon is: 180(n - 2) Since we know that one angle of this regular polygon is 171 degrees, we can find what kind of polygon it will be, using the formula: 180(n - 2) = 171n 180n - 360 = 171n 180n - 171n = 360 9n = 360 n = 360/9 n = 40 Thus the polygon is a 40-sided polygon. Check: 180(40 - 2) = 180(38) = 6840, which is the sum of the angles of the polygon. 6840/40 = 171 degrees, which is the measure of one of the angles of that polygon .

The sum of the interior angles of an n-sided polygon is 180n - 360 degrees.
144 degrees
a 7 sided polygon is heptagon and the interior angle of it is 128.57 degrees.
