Question

the measure of each exterior angle of a regular polygon is 18degree find the number of sides of polygon

Answer 1

Answer:

20 Sides

Step-by-step explanation:

Sum of Exterior angles in each regular polygon = 360°

Each Exterior angle in a regular polygon = 360°/n

( where n = number of sides in the polygon which is required in the question )

So let us put the values now,

= 360°/n = 18°

= 1/n = 18°/360°

= n = 360°/18°

= 60°/3°

= 20 Sides Ans
