That's going to depend on how many sides the polygon has. They're all different.
3 sides . . . each exterior angle = 120°
4 sides . . . each exterior angle = 90°
5 sides . . . each exterior angle = 72°
.
.
etc.
However, there's one simple way to determine what they are: they have to sum up to 360 (if you think about this for a minute, it will make a lot of sense), so each one will be 360/n where n is the number of sides.

What is the measure of a central angle of a regular ten sided polygon?
the center angle of any polygon is 360 degrees
What is the measure of a central angle for a regular polygon?
Each central angle is (360) divided by (number of sides in the polygon).
How do you measure sides of a regular polygon if each interior angle is 120?
A regular polygon with each interior angle measuring 120 degrees is a hexagon.
What is the measure of an interior of a regular polygon with 14 sides?
Two methods :_ 1) The sum of the interior angles of a regular polygon is 2n - 4 right angles. For a 14 sided polygon then (2 x 14) - 4 = 24 right angles = 24 x 90 = 2160° Therefore each interior angle = 2160 ÷ 14 = 154.29° (2dp) 2) The external angle of a 14 sided regular polygon = 360 ÷ 14 = 25.71° The interior angle = 180 - external angle = 180 - 25.71 = 154.29°
How many sides does a regular polygon have if the measure of an angle is 12?
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.
