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.

What is the formula used to calculate the number of sides in a polygon using its angle measures?

Let S be the sum of the measures of all the interior angles, in degrees. Then the number of sides is S/180 + 2.


What is the measures of the interior angles of a regular polygon if each exterior angle measures 72?

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.

What is the sum of the measures of the interior angles of a regular polygon is each exterior angle measures 120?

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.

What is the measures of the interior angles of a regular polygon if each exterior angle measures 72?

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.
