Question

find the number of sides in a regular polygon if which each interior angle is 160​

Answer 1

Answer:

18 sides

Step-by-step explanation:

Each interior angle = 160

Each exterior angle = 180 - 160 = 20

The sum of exterior angles is always 360 degrees

Let the number of sides be x

x * 20 = 360           (All angles of a regular polygon are equal)    

=> x = 18

Therefore, the polygon has 18 sides.
