Total central angle = 360 degrees. Each angle = 30 degrees so number of angles = 360/30 = 12. So the polygon would have 12 sides.
The angle sum of any polygon is 360 degrees.
Smallest possible interior angle of regular polygon is 60 degrees (triangle). The greater the number of sides, the greater each interior angle. If exterior angle is 30 degrees, the polygon has 12 sides.
A regular polygon with an exterior angle of40O is a nonagon, and has 9 sides.

Total central angle = 360 degrees. Each angle = 30 degrees so number of angles = 360/30 = 12. So the polygon would have 12 sides.
Since the sum of the n central angles (where n is also the number of sides) of a regular polygon is 360 degrees, then our polygon has 9 sides (360/40) and it is called a nonagon.
360/72 ie 5 sides
To calculate the measure of a central angle of a regular nine-sided polygon, divide 360 degrees by the number of sides. In this case, divide 360 by 9. The measure of the central angle of a regular nine-sided polygon is 40 degrees.
Central angle of a regular polygon is 360/n. n is the number of sides.
Each central angle is (360) divided by (number of sides in the polygon).
The angle sum of any polygon is 360 degrees.
Smallest possible interior angle of regular polygon is 60 degrees (triangle). The greater the number of sides, the greater each interior angle. If exterior angle is 30 degrees, the polygon has 12 sides.
how many sides does the polygon have is the interior angle is 6660 degrees? important please tell me...
If each exterior angle is 30 degrees the polygon has 360/30 = 12 sides.
