What is the exterior angle of a regular 18 sided polygon?
20 degrees. The exterior angles always add up to 360 degrees.
What are the exterior angles on a 20 sided polygon?
The sum of the exterior angles of any polygon and the extension of its adjacent side is 360 degrees.If the 20 sided polygon is regular, then each angle is equal so that each one is 360/20 = 18 degrees.
What are the interior and exterior angles of a regular 18 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=18, then the answer is that the interior angle = 160The measure of an exterior angle in degrees of a regular polygon of n sides is given by the formula: 360/nSubstituting with n= 18, then the answer is that the exterior angle = 20
If the exterior angle of a regular polygon is 20 what is the interior angle of this polygon?
160
What is the measure of the interior angle and the exterior angle of a regular polygon with 20 sides?
Each exterior angle measures 20 degrees Each interior angle measures 160 degrees
What is the measure of each exterior angle of regular 18 sided polygon?
20
What is the measure of an exterior angle of a regular 20- sided polygon?
360/20 = 18 degrees.
What is the exterior angle of an 20 sided shape?
If it's regular then 360/20 = 18 degrees
What is the size of an interior angle of a 20 sided regular polygon?
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
What is the measure of each exterior angle of a regular 18- sided polygon?
20
Interior angle for 20 sided shape?
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
What is the exterior angle of a regular 18 sided polygon?
20 degrees. The exterior angles always add up to 360 degrees.
What shape has a exterior angle of 20 degrees?
A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
What is the exterior angle of a twenty sided ploygon?
The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.
What is the size of each exterior angle of a regular twenty sided polygon?
You simply do 360/20=18 so the size of each interior angle is 18 degrees.
What is the exterior angle of an 18 sided shape?
The exterior angle of a 18 sided shape is 360/18 =20 degrees The exterior angle is always 360 divided by the numbe of sides of that polygon. =) what the hell im i doing answering this?
What are the exterior angles on a 20 sided polygon?
The sum of the exterior angles of any polygon and the extension of its adjacent side is 360 degrees.If the 20 sided polygon is regular, then each angle is equal so that each one is 360/20 = 18 degrees.
