The polygon is a regular nonagon (9-sides). What is the sum of the interior angles? What is the measurement for each angle?

To solve the problem we will first calculate the sum of all the interior angles.

The sum of all the interior angles of n numbered polygon is given as,

the sum of all the interior angles of n numbered polygon = (n-2) x 180°.

Given to us

A.)  the sum of the interior angles,

the sum of the interior angles = (n-2) x 180°

                                                   = (9-2) x 180°

                                                   = (7) x 180°

                                                   = 1,260°

Thus, the measurement of the sum of the interior angles of a 9 sided polygon is 1260°.

B.) the measurement for each angle

Hence, the measurement of each angle of a 9 sided polygon is 140°.

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
