Question

The exterior angle of a regular polygon is 120 degree, Find the number of sides.

Answer 1

Hello friend!

Exterior angle = 120°
Since it is a regular polygon,
Sum of all ext. angles of n sided polygon = 360°
Number of sides of polygon = 360°/Each angle = 360°/120° = 3 sides

Hope it helps!

$\bf\large\color{Red}{Hello\:brainy\: User \: :) }$

⚽ Given that :
Exterior angle of regular polygon is 120°.

⚽ To find :
No. of Sides of the polygon.

=> No. of sides = 360/Measure of an Angle.
=> 360/120
=> 3 sides.

So, the polygon constitutes 3 sides.

Hope it helps you☺☺
