Best Answer

The formula is normally: (n-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon

Q: Can the measure of interior angle of a regular polygon can be found using 2 n-4 x 9 if n equals number of sides?

The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.

If it is a regular polygon with each interior angle of 120 degrees then it is an hexagon which will have 0.5((6^2)-3*6) equals 9 diagonals

If it is a regular polygon then it will have 360/12 equals 30 sides

Providing that it's a regular polygon it will have 16 sides.

The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.

The measure of one interior angle of a regular polygon with 20 sides is 162Â°.The general rule to find the measure of the interior angle of a polygon with n sides is:( n - 2 ) * 180Â° / nIn the case of our 20-gon, n equals 20, so...( 20 - 2 ) * 180Â° / 2018 * 180Â° / 203240Â° / 20162Â°

if the interior angle is 150 the exterior angle equals 30. since exterior angle equals 360/ by number of sides the number of sides equals 360/30 which equal 12
