HEYA!!
---------

Measure of exterior angle of the polygon = 18 °

Number of sides : ?

$= >number \: of \: sides \: \: = \frac{360}{measure \: of \: exterior \: angle \: }$
We have ,

= 360 / 18

= 20 sides .

sania7287: is this correct

sania7287: answer

DevilDoll12: yes correct

sania7287: ohk

shadowsabers03: Yeah, this is right answer.

shadowsabers03: Ananya, if 360 divided by one exterior angle gives no. of sides, then it should be a regular polygon. Remember that. If it is not regular, we can't find by dividing 360 by the angle. It had better explain that in your answer.

Answered by shadowsabers03

Sum of exterior angles of a polygon is 360°.

Here, it is a regular polygon. So 360 divided by 18 gives the number of sides.

∴ 360 ÷ 18 = 20

∴ The regular polygon has 20 sides.
