Best Answer

- The measure of an interior angle in degrees of a regular polygon of n sides is given by the formula: 180 x (n-2) / n

Substituting with n=9, then the answer is that the interior angle = 140

- The measure of an exterior angle in degrees of a regular polygon of n sides is given by the formula: 360/n

Substituting with n= 9, then the answer is that the exterior angle = 40

Each exterior angle of a regular polygon with n sides is 360/n degrees. Each interior angle of a regular polygon is 180 - Exterior angle. A direct formula for the interior angle is 180*(n-2)/n degrees.

If the polygon has n sides, each exterior angle is 360/n degrees.The interior angle is 180 less exterior angle.

Exterior angle regular polygon = 360° ÷ number of sides = 360° ÷ W Interior angle regular polygon = 180° - exterior angle regular polygon = 180° - (360° ÷ number of sides ) = 180° - (360° ÷ W)

Interior angle = 120 degrees Exterior angle = 60 degrees

360 ________________________________________________ Sum of Interior Angles of a Polygon = 180 (n-2) Sum of Exterior Angles of a Polygon = 360 The sum of an angle and an exterior angle of a regular polygon is 360

180-interior angle = exterior angle If it's a regular polygon then: 360/number of sides = exterior angle

Exterior angle 12 degrees Interior angle 168 degrees

A regular polygon of 30 sides will each have an exterior angle of 12 degrees and an interior angle of 168 degrees.

180-interior angle = exterior angle 360/exterior angle = number of sides

It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line

Each interior angle is 165 degrees Each exterior angle is 15 degrees
