Calculate the number of sides of a regular polygon, if :
(i) its interior angle is five times its exterior angle.
(ii) the ratio between its exterior angle and interior angle is 2 : 7.
(iii) its exterior angle exceeds its interior angle by 60o.
If the sum of the interior angles of a regular polygon is five times the sum of its exterior angles, then the number of sides it has is
If the sum of exterior angles of a polygon is one - ninth the sum of its interior angles, then the polygon has ___ sides.
