First off do
X-2
then (X-2) x 180. There is your answer
For example,
15-2 = 13
13 x 180 = 2340.
so a 15 sided polygon has an angle sum of 2340.
2340 degrees
The sum of the interior angles of a 15-gon add up to 2340 degrees
Providing thar it is a regular 15 sided polygon then each interior angle will be 156 degrees
Providing that it is a regular 15 sided polygon then each interior angle will be 156 degrees
Sum of exterior angles = 360 deg Number of exterior angles = 360/24 = 15 So it is a 15-sided polygon
The angles in a 15 sided polygon add up to 2340 degrees
The interior angles of a 15 sided polygon add up to 2340 degrees
2340 degrees
2340 degrees
(15-2)*180 =2340
sum of interior angles of EVERY n-sided polygon is 180n - 360 degrees. When n = 15 sum is 2340 degrees.
The interior angles of a 15 sided polygon add up to 2340 degrees.
The sum of the interior angles of a 15-gon add up to 2340 degrees
Remember Exterior angle = 360 / No. of sides. Hence Exterior Angle = 360//25 = 24 degrees, It follows that the intertiot angle is 180 - 24 =156 degrees. There are 15 interior angles Hence 15 x 156 = 2340 degrees is the sum of the interior angles of a 'Pentadecagon'.
Sum of interior angles of any n-sided polygon is (2n - 4) right angles ie 26 x 90 which is 2340 degrees.
sum of all angles= 180(sides-2) Answer=156 degrees
Providing thar it is a regular 15 sided polygon then each interior angle will be 156 degrees
