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.
Each central angle is (360) divided by (number of sides in the polygon).
Each interior angle of a regular 10 sided decagon measures 144 degrees
the center angle of any polygon is 360 degrees

The interior angle and central angle are supplementary, that is they always add up to 180 degrees, while the exterior angle and the central angle will always be the same.
