Find the size of an exterior angle of a regular nonagon (a 9 sided figure).
How do I find it?
The sum of the exterior angles of a regular polygon is 360º
So divide 360 by 9
To find the size of an exterior angle of a regular nonagon, you can use the formula:
Exterior Angle = 360 degrees / Number of sides
In this case, the number of sides is 9 since it is a regular nonagon.
Therefore, the size of an exterior angle of a regular nonagon is:
Exterior Angle = 360 degrees / 9 sides
= 40 degrees
