**How many sides does a regular polygon have if each of its interior angles is 165 ∘ ?**

A) 24

B) 44

C) 55

D) 33

**Answer:**

A) 24

**Explanation:**

- Interior angle of a given polygon =165o
- The exterior angle of a polygon $=18_{o}−16_{o}=1_{o}$
- The sum of exterior angles of any polygon is $36_{o}$
- Number of sides of a regular polygon $=15o360o =24$
