​

Answer 1

Question ⤵️

find the measure of an interior angle of aregular polygon of 9 sides.

Answer ⤵️

To find the value of an internal angle within this polygon, we can just multiply the number of triangles by 180 ° , then divide by the number of internal angles, which is nine. Excellent! So the interior angle of a 9 -sided polygon is

140°.

Answer 2

☆ Correct Question ☆

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

☆ Solution ☆

Given :-

• Side = 9

To Find :-

• The measure of an interior angle of a regular polygon.

Step-by-Step-Explaination :-

Sum of interior angle = ( n - 2 ) × 180

= ( 9 - 2 ) × 180

= 7 × 180

Measure of one interior angle

= 7 × 180/9

= 7 × 20

= 140

Hence,

The measure of an interior angle of a regular polygon of 9 side = 140°.
