Well here's an easy way. Well the formula for finding each exterior angle for a polygon with x sides is 360/x. Well to find the interior angle, you need to do (180 - (your result for you previous division)), and voila! Then you find out how many interior angles there are, and multiply the answer by that number. You're done.
The sum is: (11-2)*180 = 1620 degrees
The 20 interior angles add up to 3240 degrees
The interior angles of a 24-agon add up to 3960 degrees.
The sum of the interior angles is (n-2)*180 degrees.
The interior angles of an 11-gon add up to 1620 degrees
2340
Sum= 2340 Degrees A+
The sum of the interior angle is (n - 2)*180 degrees.
The sum is 95*180 = 17,100 degrees
The sum is: (11-2)*180 = 1620 degrees
The sum of the interior angles of a 15-gon is (15-2)x180 degree which is 13x180 degrees or 2340 degrees.
The 20 interior angles add up to 3240 degrees
the sum of the interior angles of a 35-gon.
The sum of interior angle ( Sum-of-interior-angles-n-gon) of n-gon is:If we have a ,Then
The interior angles of a 24-agon add up to 3960 degrees.
The sum of the interior angles is (n-2)*180 degrees.
find the sum of the measures of the interior angles of 13-gon.
