If it is a regular nonagon, then you use the following formula:

[(s-2) x 180]/s = angle of one interior angle. (s means the number of sides)

Then solve: [(s-2) x 180]/s = [(9-2) x 180]/9 = [7 x 180]/9 = 1260/9 = 140.

Then, for the exterior angle, subtract 140 from 360. The measure of the exterior angle of a regular nonagon is 220.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the measure of each exterior angle of a regualer nonagaon?

The formula for an exterior angle is 180-(180/n)(n-2) where n is the number of sides. For a nonagon the number of sides is 9. Plugging this into the equation gives: 180-(180/9)(9-2) =180-(20)(7) =40 So the exterior angles of a regular nonagon will measure 40 degrees.
