Question

find the number of sides of a regular polygon whose each interior angles measures 140°​

Answer 1

Answer:

9 sides.

Explanation:

Interior angle=140°

When extended, it will form a linear pair with the exterior angle.

So,  exterior angle=180°-140°=40°

Also, the sum of exterior angles in any polygon is 360°

Therefore, number of sides=360°/40°=9 sides
