Question

If the measure of each exterior angle of a regular polygon is 18°, determine how many sides the polygon has.

Answer 1

we are given

exterior angle is 18

so,

`\theta=18`

now, we can use formula

number of sides of regular polygon = 360/(exterior angle)

so, we get

`n=(360)/(18)`

`n=20`

so, number sides is 20..........Answer
