360/number of sides = exterior angle
If each exterior angle is 9 degrees then it is a regular 40 sided polygon.
Each exterior angle is 72 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).
Exterior angle of ANY regular n-sided polygon is 360/n degrees...
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

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).
It is a regular 10 sided decagon
