Question

Geometry math question no Guessing and Please show work thank you

Answer 1

108n=180(n-2)

108n=180n-360

72n=360

n=5 sides

so, option-A...........Answer hope this helps:)

Answer 2

we know that

formula of each interior angle of regular polygons

`\theta=(180(n-2))/(n)`

where

theta is angle

n is number of sides

we are given

theta=108

so, we can set it equal

`108=(180(n-2))/(n)`

now, we can solve for n

`108n=180(n-2)`

`108n=180n-360`

`72n=360`

`n=5`

so, option-A...........Answer
