If it is a regular nonagon, then you use the following formula:
[(s-2) x 180]/s = angle of one interior angle. (s means the number of sides)
Then solve: [(s-2) x 180]/s = [(9-2) x 180]/9 = [7 x 180]/9 = 1260/9 = 140.
Then, for the exterior angle, subtract 140 from 360. The measure of the exterior angle of a regular nonagon is 220.

How many sides does the regular polygon have if each interior angle measure is four times the measure of each exterior angle measure?
It will have 10 sides and each interior angle measures 144 degrees while each exterior angle measures 36 degrees
What is the size of each exterior angle of a regular nonagon a 9 sided shape?
360/9 = 40 degrees
How do you find the measure of each exterior angle of a regular pentagon?
It is: 360/5 = 72 degrees for each exterior angle and each interior angle will be 108 degrees
What is the measure of each exterior angle and each interior angle of nonagon?
Providing that it is a regular nonagon then each exterior angle measures 40 degrees and each interior angle measures 140 degrees
What is each exterior angle measure of a regular nonagon?
40 degrees
What is the measure of each interior angle and each exterior angle of a regular nonagon?
Each interior angle is 140 degrees. Each exterior angle is 220 degrees.
What is the measure of each interior and each exterior angle of a regular nonagon?
Each exterior angle: 40 degrees Each interior angle: 140 degrees
Find the measure of each exterior angle of a regular nonagon?
The measure is 360/9 = 40 degrees.
What is the measure of each exterior angle of a regular monagon?
If you mean each exterior angle of a regular 9 sided nonagon then it is 360/9 = 40 degrees
What is the exterior angle of a regular nonagon?
Each exterior angle is: 360/9 = 40 degrees
What is the sum of the measure of the exterior angles of a regular nonagon?
All exterior angles of any polygon sum to 360 deg. If there are 9 angles then each angle is 40 degrees.
What is the measure of each exterior angle of a regualer nonagaon?
The formula for an exterior angle is 180-(180/n)(n-2) where n is the number of sides. For a nonagon the number of sides is 9. Plugging this into the equation gives: 180-(180/9)(9-2) =180-(20)(7) =40 So the exterior angles of a regular nonagon will measure 40 degrees.
What is the number of sides of a polygon if each of its exterior angles measure 140?
The exterior angle would have to be greater than 180 degrees. If you mean interior angle then a regular nonagon (9 sided) will have angles of 140 degrees.
What is the measure of each exterior angle of a regular 40-gon?
Each exterior angle will measure 9 degrees
What does each exterior angle of a regular nonagon equal to?
360/9 = 40 degrees
