Question

Find the sum of the interior angles. please I need help!!

Answer 1

Given:

A 7-sides regular polygon.

To find:

The sum of the interior angles of the given regular polygon.

Solution:

The formula for the sum of the interior angles of a regular polygon is:

`Sum=180^\circ(n-2)`

Where, n is the number of sides of the regular polygon.

The given regular polygon has 7 sides. Putting
`n=7` in the above formula, we get

`Sum=180^\circ(7-2)`

`Sum=180^\circ(5)`

`Sum=900^\circ`

Therefore, the sum of the interior angles of the given regular polygon is 900 degrees.
