Each exterior angle of a regular polygon is 400. The number of sides of the polygon is -
6
7
9
None of these
Measure of exterior angle of an `n' sided regular polygon = 2×1800n = 400 n = 9
In a regular polygon each interior angle is 120 degree grater than each exterior angle. Calculate the number of side of the polygon.
The interior angle of a regular polygon is double the exterior angle. The number of sides of the polygon is
The rario between the interior angle and the exterior angle of a regular polygon is 2 : 1. Find :
(i) each exterior angle of the polygon ;
(ii) number of sides in the polygon.
