What is the angle sum for a 9 sided polygon?
1620
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.
Each interior angle of a regular polygon is 140 How many sides has the polygon?
Interior angle = 140 deg so exterior angle = 40 deg. Sum of exterior angles = 360 so 360/40 = 9 such angles required. So the figure has 9 sides.
How many sides does a regular polygon have if the measure of the angle is 171?
If each interior angle is 171 degrees then each exterior angle is 180-171 = 9 degrees. Sum of all exterior angles (irrespective of number of sides) is 360 degrees So number of sides = 360/9 = 40
What is the interior angle of a 9 sided polygon?
Ah, let's paint a happy little picture of a 9-sided polygon, also known as a nonagon. To find the interior angle of a regular nonagon, we use the formula (n-2) * 180 degrees / n, where n is the number of sides. So for a nonagon, it would be (9-2) * 180 degrees / 9, giving us an interior angle of 140 degrees. Isn't that just delightful?
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 measure of each exterior angle of a 9-sided polygon?
40
What is the size of each exterior angle of a 9 sided polygon?
360 / 9 = 40
What is the measure of each exterior angle of a regular 9-sided polygon?
40
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
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 the exterior angle of a regular 9 side polygon?
400 exterior angle = 360/9 = 400
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.
What is the angle sum for a 9 sided polygon?
1620
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.
Calculate the measure of a central angle of a regular nine- sided polygon?
Each central angle of a regular 9 sided polygon: 360/9 = 40 degrees
Interior angle of 9 sided polygon?
140 degrees
