Interior angles total = 180n - 360
so 180n = 360 + total
ie n = (360 + total)/180
eg for a triangle, total = 180 so n = 540/180 ie 3 which is correct.
Let S be the sum of the measures of all the interior angles, in degrees. Then the number of sides is S/180 + 2.
The interior angle of any regular polygon can be calculated using the formula 180 * (n - 2) / n, where n is the number of sides. In this case, since each exterior angle measures 72 degrees, the interior angle would be 180 - 72 = 108 degrees. So the measures of the interior angles in this regular polygon would be 108 degrees.
(number of sides-2)*180 = sum of interior angles
To find the sum of the measures of the interior angles of a regular polygon with each exterior angle measuring 120 degrees, we first determine the number of sides in the polygon. The sum of exterior angles of any polygon is always 360 degrees, so the number of sides ( n ) can be calculated as ( n = \frac{360}{120} = 3 ). Since it is a triangle, the sum of the interior angles is given by the formula ( (n - 2) \times 180 ) degrees, which for a triangle (3 sides) is ( (3 - 2) \times 180 = 180 ) degrees. Thus, the sum of the measures of the interior angles is 180 degrees.
Formula: sum of interior angles = (n-2) x 180 where: n=number of sides = (8-2) x 180 =6 x 180 =1080 degrees
(number of sides-2)*180 = total sum of interior angles
(n-2)180 is the formula for the sum of the interior angles. Since n = the number of sides, the answer is (36-2)180 = 6,120 degrees.
Let S be the sum of the measures of all the interior angles, in degrees. Then the number of sides is S/180 + 2.
(number of sides -2)*180 = sum of interior angles.
The sum of the interior angles of an n-gon is given by the formula (n-2)(180) where n is the number of sides of the polygon. Thus, the sum of the interior angles of an 18-gon is (18-2)(180) = 2880.
(number of sides-2)*180 = sum of interior angles of a polygon
(number of sides-2)*180 = sum of interior angles
The interior angle of any regular polygon can be calculated using the formula 180 * (n - 2) / n, where n is the number of sides. In this case, since each exterior angle measures 72 degrees, the interior angle would be 180 - 72 = 108 degrees. So the measures of the interior angles in this regular polygon would be 108 degrees.
Use the formula (n - 2)180 to find the sum of the measures of the interior angles of any regular convex polygon, where n is the number of sides. (n - 2)180 = (18 - 2)180 = (16)180 = 2880
The formula to find the sum of interior angles of a polygon is 180° × (n - 2), where n is the number of sides of the polygon.
Formula: sum of interior angles = (n-2) x 180 where: n=number of sides = (8-2) x 180 =6 x 180 =1080 degrees
It is: (n-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
