Question

how many sides does a regular polygon have if each of it's interior angle measures 108°?​

Answer 1

Step-by-step explanation:

Each interior angle of the polygon is 108 degrees, so each exterior angle of the polygon is 180-108 = 72 degrees. So the number of sides is 360/72 = 5.

Answer 2

answer

the correct answer is 5

it's called pentagon

you can also find by using the formula

each interior angle =sum of all interior angles /number of angles

so,108=n-2×180/n

108n=180n-360

360 = 72x

360/72=x

5=x
