Answer 1

180(n−2)n=108°


180n−360=108n

72n=360

n=5

mark as brainliest please

Answer 2

Answer:

if each interior angle is 108 then ,

each exterior angle is 180 -108 = 72

So, the no. of sides =        360                    

                                   each  exterior angle

                                 = 360/72

                                 = 5
