Question

Find the measure of an interior angle of a regular polygon of 9 sides.​

Answer 1

Given,

Regular polygon has = 9 sides

To find,

The measure of each interior angle.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now,

Measure of each interior angle of any regular polygon :

$= \frac{(n - 2) \times 180°}{n}$

(Here, n = number of sides of the regular polygon.)

By putting the given values, we get,

$= \frac{(9 - 2) \times 180°}{9}$

$= \frac{7 \times 180°}{9}$

$= 7 \times 20°$

$= 140°$

(This will be considered as the final result. And, this measure of interior angle is true of any 9 sided regular polygon.)

Hence, measure of each interior angle is 140°
