Each exterior angle = 360/number of vertices = 360/9 = 40 degrees.Each interior angle = 180 - exterior angle = 180 - 40 = 140 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
How do you find the interior angle of a regular poloygon?
360 /each exterior angle
What is the measure of an interior angle for a regular ten-sided polygon?
144o. Sum of exterior angles of a polygon is 360o. Each exterior angle for a regular decagon is 360o / 10 = 36o. Exterior and interior angles are supplementary, that is sum to 180o. Therefore the interior angle of a regular decagon is 180o - 36o = 144o.
Give the formulas for finding the number of sides of a regular polygon when given the measure of an interior angle?
180-interior angle = exterior angle 360/exterior angle = number of sides
How many sides does a regular polygon have with one interior angle measuring 140 degrees?
If the interior angle = 140 degrees, then the exterior angle = 180 degrees - 140 degrees = 40 degrees. So the number of sides is 360 degrees / 40 degrees = 9 sides (a nonagon).
What is the interior and exterior of a regular nonagon?
Exterior angle 40 degrees Interior angle 140 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 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
What is the degree measurement of each angle of a nonogon?
Providing it is a regular nonagon: Exterior angle: 40 degrees Interior angle: 140 degrees
What is the measure of an interior angle and an exterior angle of a nonagon?
The sum of the interior angles of a polygon is 2n-4 Right Angles For a nonagon (2x9)-4 RAs = 14x90°=1260° To find the interior angle of a regular nonagon, divide this by 9 which gives 140° To find the exterior angle, subtract this from 180 and you get 40°. The sum of the exterior angles of a polygon is 360°, so for a regular polygon you can also divide this by the number of sides, which in this case also gives: 360° ÷ 9 = 40°
What is each exterior angle measure of a regular nonagon?
40 degrees
What is the measure of each exterior angle of nonagon?
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.
