The sum of the interior angles of a 30-gon is (30-2)*180 = 5040 degrees. So each interior angle of a 30-gon is 5040/30 = 168 degrees.
10440
The sum of the interior angles of a 15-gon is (15-2)x180 degree which is 13x180 degrees or 2340 degrees.
It's often easier to calculate the external angle and subtract this result from 180 to obtain the interior angle. External angle of a 35-gon = 360/35 = 10.2857° Interior angle of a 35-gon = 180 - 10.2857 = 169.7143° The formal way is to use the formula that the Sum of the interior angles = 2n - 4 right angles.....where n is the number of sides. Sum of interior angles = [(2 x 35) - 4] x 90 = 66 x 90 = 5940 Then each interior angle = 5940 / 35 = 169.7143°
Sum of interior angles =(no. of sides - 2)180 =(55-2)180 =9540 degrees
3240 degrees
Interior angles: 5940
The interior angles add up to 2340 degrees
The sum is: (11-2)*180 = 1620 degrees
If the 35-gon is a regular one, then its interior angle measure equals to [(35 - 2)180⁰]/35, which is approximately 169.72 degrees.
The sum of interior angle ( Sum-of-interior-angles-n-gon) of n-gon is:If we have a ,Then
The sum of the interior angles of a 15-gon add up to 2340 degrees
The sum of the interior angles of a 30-gon is (30-2)*180 = 5040 degrees. So each interior angle of a 30-gon is 5040/30 = 168 degrees.
The sum of the interior angles is (28-2)*180 = 4680 degrees.
Any angle that you like. The only constraint is that the sum of all 18 interior angles is 2880 degrees.
The sum of the interior angles of a 16-gon is (16-2)*180 = 2520 degrees. The measure of each interior angle cannot be determined unless the polygon is regular.
