Question

find the measure of each interior angles of a regular nonagon​

Answer 1

=(n-2)×180
=(9-2)×180
=7×180
=1260°

One angle = 1260/9
=140°


Hope it helps uhh❤❤❤

Answer 2

Answe;

Each interior angle in Nonagon = 140°

Step-by-step explanation:

Given problem

Find the measure of each interior angles of a regular nonagon​

Number of sides in nonagon = 9

In a regular polygon sides and angles are equal

and interior angle in a polygon = $\frac{(n-2)(180}{n }$  

here n is number of sides in the polygon

interior angle in nonagon = $\frac{(9-2)(180)}{9}$

                                          = $\frac{7(180)}{9}$  

                                          = 7(20) = 140°
