Question

Each exterior angle of a certain regular polygon measures 30. How many sides does the polygon have?

Answer 1

Number of sides of the polygon is `12`.

Explanation:

Sum of exterior angles of every polygon irrespective of number of its sides is `360^o`.

As it is a regular polygon, all exterior angles are equal and are `30^o`.

Hence number of sides of the polygon is `360^o/30^o=12`.
