The interior angles of a 1260 sided polygon add up to 226,440 degrees and its exterior angles add up to 360 degrees
1260 degrees
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
9099 * * * * * The sum of the interior angles is (9 - 2)*180 = 1260 degrees.
A nonagon is a 9 sided polygon whose 9 interior angles add up to 1260 degrees
A 9 sided nonagon has interior angles that add up to 1260 degrees
140 degrees
The interior angles of a 1260 sided polygon add up to 226,440 degrees and its exterior angles add up to 360 degrees
1260 degrees
A 9 sided nonagon has interior angles that add up to 1260 degrees
A 1260 degree polygon has nine sides. The formula for determining this is (n*180)+2, with n being equal to the degrees in the interior of the polygon.
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
(2n - 4) x 90 = 1260 where n is the number of sides.ie 180n = 1260 + 360n = 1620/180 = 9Your polygon is a nonagon (or enneagon)
Suppose the polygon has n sides. Then (n - 2)*180 = 1260 So (n - 2) = 1260/180 = 7 and therefore, n = 7 + 2 = 9
Well, darling, the angle sum of a polygon with 9 sides is 1260 degrees. Each interior angle of a regular nonagon measures 140 degrees. So, if you add up all those interior angles, you get 1260 degrees. Math doesn't have to be a drag, honey!
1260/9 ie 140 degrees assuming polygon is regular. Total is not affected by regularity.
It has 9 sides and is called a nonagon
