interior: (n-2)180/n
exterior: 360/n
(n-2)180/n ÷ 360/n = (n-2)/2 = 5
n = 8
a:
exterior: 45
interior: 135
b: n=8
c: 6(180) = 1080
d: octagon
exterior: 360/n
(n-2)180/n ÷ 360/n = (n-2)/2 = 5
n = 8

Oops
n=12
exterior: 30
interior: 150
n=12
10(180) = 1800
dodecagon
n=12
exterior: 30
interior: 150
n=12
10(180) = 1800
dodecagon
