Providing that it's a regular polygon then each exterior angle will measure 12 degrees.

It is a regular 10 sided decagon
For the 12-sided polygon, each exterior angle is 30 degrees (360/12).
If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.
If its a regular 9 sided polygon then the exterior angles are 40 degrees.
The measure of 1 exterior angle of a regular 8-sided polygon is equivalent to 45 degrees. Hope I helped! :)
Providing that it is a regular 12 sided polygon then each exterior angle measures 30 degrees
360/number of sides = exterior angle
If each exterior angle is 9 degrees then it is a regular 40 sided polygon.
Providing that it's a regular polygon then each exterior angle will measure 12 degrees.
Each exterior angle measures 36 degrees
Each exterior angle is 72 degrees
Each exterior angle measures 15 degrees

A regular 6-sided polygon has exterior angles of 60o(360o/6)If it is not regular, and one interiorangleis 140o, then the exterior angle at that vertex is 40o (180-40).
