Each angle theta is (n-2)/n) x 180 degrees
The sum of all angles is nx theta = (n-2) x 180
sum = 180 n - 360
sum + 360 = 180 n
n = (sum + 360)/180 = sum/180 + 2
So you divide sum by 180 then add 2
Because; (number of sides-2)*180 = sum of interior angles
(number of sides-2)*180 = sum of the interior angles
The formula for the sum of the interior angles of a polygon is: 180 * (n - 2) where n is the number of sides of the polygon. So the sum of the angles of a polygon with 25 sides is 180 * 23 = 4,140.
(number of sides - 2)*180 = total sum of interior angles
(number of sides -2)*180 = sum of interior angles
(number of sides-2)*180 = total sum of interior angles
(number of sides-2)*180 = sum of interior angles of a polygon
Because; (number of sides-2)*180 = sum of interior angles
(number of sides-2)*180 = sum of the interior angles
The formula for the sum of the interior angles of a polygon is: 180 * (n - 2) where n is the number of sides of the polygon. So the sum of the angles of a polygon with 25 sides is 180 * 23 = 4,140.
(number of sides -2)*180 = sum of interior angles.
(number of sides - 2)*180 = total sum of interior angles
It is: (n-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
(number of sides -2)*180 = sum of interior angles
8 sides
There is no single formulaImproved Answer:-(number of sides -2)*180 = number of the sum of interior angles
When the sides of a regular polygon increases its interior angles also increases
