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 central angle is (360) divided by (number of sides in the polygon).

360 degrees ( all the way round the central point). However, for one given sector it is 360/12 = 30 degrees.
