If its a regular 9 sided polygon then the exterior angles are 40 degrees.

Each exterior angle = 360/number of vertices = 360/9 = 40 degrees.Each interior angle = 180 - exterior angle = 180 - 40 = 140 degrees.

Each exterior angle: 40 degrees Each interior angle: 140 degrees

Any polygon can have a 40-degree angle. It doesn't have to, but it can.

Since the interior angle measure of the regular polygon is 140⁰, its exterior angle measure is 180⁰ - 140⁰ = 40⁰. Since the sum of the exterior angle measures is 360⁰, the polygon has 360⁰/40⁰ = 9 sides.

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).

If you mean each exterior angle of a regular 9 sided nonagon then it is 360/9 = 40 degrees

Interior angles total 40 - 4 right angles, ie 36 x 90o, so each interior angle is 18 x 9 ie 162o and the exterior is 180 - 162 = 18o
