360 degrees ( all the way round the central point). However, for one given sector it is 360/12 = 30 degrees.
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.

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.
It can have any value at all. A definite value can be determined if the polygon is regular, but there is no justification for assuming that to be the case.
Each interior angle of a regular 10 sided decagon measures 144 degrees
Each central angle is (360) divided by (number of sides in the polygon).

The central angle of a n-sided regular polygon = 360 degrees / n. Hence, the central angle of a 15-sided regular polygon = 360 degrees / 15 = 24 degrees ============================
