Measure of an exterior angle of a 12-gon?
To find an exterior angle of a regular 12-gon, use the formula to find the total sum of all the angles first: total sum of all angles = (n-2)*180where 'n' is the number of sides, or 12.By solving, you will find that the total sum of all angles is 1800 degrees, so since it is a regular polygon, you can divide by 12 to find the measure of each interior angle, which is 150 degrees.Once you know the measure of the interior angles, since an exterior angle is the supplement of an interior angle, subtract 150 degrees from 180 degrees (the measure of a straight line) to find the exterior angles, which will be 30 degrees.
Find the sum of exterior angles of a convex 21-gon?
The angles add up to 3420 degrees. In a regular 21-gon, each angle is about 162.86 degrees.
How many exterior angles are there in an n-gon?
NONE
What is the sum of the exterior angles in an 11-gon?
The exterior sum of angles of any polygon is always 360 degrees.
Measures of an exterior angle of 20-gon?
Well, honey, an exterior angle of a polygon can be found by dividing 360 degrees by the number of sides. So for a 20-gon, each exterior angle would be 18 degrees. It's as simple as that, darling.
Is the measure of a 9-gon exterior angles greater than the measure of a 4-gon exterior angles?
5
What is the measure of the exterior angles of a regular 11-gon?
It is: 360/11 degrees for each exterior angle
How do you find the measure of each exterior angle of a regular 20-gon?
The exterior angles add up to 360 degrees. So: 360/20 = 18 degrees
How do you find the number of sides a regular poly gon has by knowing the angles?
When a polygon is regular, each exterior angle is equal to the other exterior angles. Since the sum of all the exterior angles is 360 degrees, if you divide 360 by the measure of one exterior angle, you will get the number of sides. If you instead have the measure of an interior angle, simply calculate (180 - interior angle measure) to find the measure of the exterior angle, and use the above paragraph.
How do you find the measure of a regluars polygon that is a 10-gon?
The answer will depend on what measure you are interested in: interior or exterior angles, lengths of sides, principal diagonals, apothem, area.
What is the sum of the measure of the exterior angles of a convex 39-gon?
The sum of the exterior angle of ANY polygon is 360 degrees.
Find the sum of the exterior angles of a 32-gon?
Number of sides is irrelevant, exterior angles always total 360o

What is the answer for each exterior angles of the regular n-gon has a measure of 3 degrees?
120 degrees
What is the sum of the measures of the exterior angles of a 23-gon?
What is the sum of the exterior angles of a 23 gon
How do you find the measure of an interior and exterior angle of a 15-gon?
Example: a regular 15-gon The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 180 x 13 = 2340 There are fifteen angles. 2340/15 = 156 An interior angle of a regular 15-gon is 156 degrees. There are two ways to find the exterior angles. The interior and exterior angles add up to 180. 180 - 156 = 24. The exterior angles of any polygon add up to 360. 360/15 = 24
Find the sum of exterior angles of a convex 21-gon?
The angles add up to 3420 degrees. In a regular 21-gon, each angle is about 162.86 degrees.
