exterior angle = 360 divided by the number of sides
e = 360/s
40 = 360/s
multiply each side by s
40s = 360
divide each side by 40
s = 9
9 sides

Find the measures of an interior angle and an exterior angle of a regular polygon with 9 sides?
Each interior angle: 140 degrees Each exterior angle: 40 degrees
If the measure of one interior angle of a regular polygon is 140 degrees how many sides does the polygon have?
Since interior angle+exterior angle=180 degrees We can find out the exterior angle by doing 180-140=40 degrees. To find out the number of sides we simply do 360/40=9 So the polygon has 9 sides.
If each exterior angle of a regular polygon measures 40 degrees what is the total number of sides in the polygon?
If each exterior angle of a regular polygon measures 40 degrees, the polygon is a nonagon (9-sided polygon).
What is the measure of an exterior angle of a 40-gon?
Finding the exterior angle of a regular polygon is really simple, divide 360 by the number of sides. So: 360/40=9 degrees.
What is the interior and exterior angle of a regular 9 sided polygon?
The measure of an interior angle in degrees of a regular polygon of n sides is given by the formula: 180 x (n-2) / nSubstituting with n=9, then the answer is that the interior angle = 140The measure of an exterior angle in degrees of a regular polygon of n sides is given by the formula: 360/nSubstituting with n= 9, then the answer is that the exterior angle = 40
What polygon has the exterior angle measurement of 9?
If each exterior angle is 9 degrees then it is a regular 40 sided polygon.
What is the exterior angle of a 9 sided polygon?
If its a regular 9 sided polygon then the exterior angles are 40 degrees.
How many sides has a rectangular polygon with an exterior angle of 40 degrees?
A regular polygon with an exterior angle of40O is a nonagon, and has 9 sides.
If each exterior angle of a regular polygon contains 40 degrees how many sides does the polygon have?
The sum of the exterior angles of a regular polygon equal 360° .If one such angle measures 40° then the polygon has 360/40 = 9 sides.
If the exterior angles measure 40 degrees in a polygon how many sides does the polygon have?
if the exterior angle is 40 degrees the interior angle of the polygon is 180- 40 = 140 degrees. The equation for sides N is interior angle = 180 x (N-2)/N; solving you find N = 9 sides
Find the measures of an interior angle and an exterior angle of a regular polygon with 9 sides?
Each interior angle: 140 degrees Each exterior angle: 40 degrees
What is the name of polygon that has 40 degrees exterior angle?
Providing that it is a regular polygon then it is a nonagon which has 9 sides
If the measure of one interior angle of a regular polygon is 140 degrees how many sides does the polygon have?
Since interior angle+exterior angle=180 degrees We can find out the exterior angle by doing 180-140=40 degrees. To find out the number of sides we simply do 360/40=9 So the polygon has 9 sides.
If each exterior angle of a regular polygon measures 40 degrees what is the total number of sides in the polygon?
If each exterior angle of a regular polygon measures 40 degrees, the polygon is a nonagon (9-sided polygon).
One exterior angle of a regular polygon measures 40 degrees?
Then it will have 9 equal sides.
What is the exterior and interior angles of a regular polygon with 9 sides?
Exterior angle = 360*9 = 40 degrees. So interior angle = 180 - 40 = 140 deg
What is the number of sides of a regular polygon if one angle measures 140 degrees?
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.
