Question

find the sum of interior angles of nonagon​

Answer 1

Answer:

1260°

Step-by-step explanation:

(n-2)180

(9-2)180

7×180

1260°

Answer 2

Given:

A nonagon

To find:

The sum of interior angles

Solution:

The required sum is 1,260°.

We are given a polygon that has nine sides.

Also, the nonagon's interior angles' sum will be calculated as follows-

Angles' sum= (N-2)×180°

Here, the total edges of the given polygon are N.

So, N=9.

We will use the total number of edges to obtain the sum.

Using N=9, we get

Required sum=(9-2)×180°

=7×180°

=1,260°

Therefore, the required sum is 1,260°.
