What is the measure of an exterior angle of a regular nonagon?
- A40
∘ - B45
∘ - C36
∘ - D60
∘
Solution & Step-by-step Explanation
A regular nonagon has n=9 sides.
The sum of all exterior angles of any polygon is 360
∘
.
For a regular polygon, each exterior angle is equal and given by:
Exterior Angle=
n

∘
Exterior Angle=
