-26 is not an inequality. It's just a number. Maybe there was
another part of it that you forgot to copy.
11c-4c = 7c
5c+2c= 7c
3c+7c= 10c
11c-4c= 5c+2c =A
That would be A...they have to have a constant ratio
let the number of sides be n.
Thus,
(n-2)x180=330
n-2=1.83
n=3.83
Rounding off we have, n=4.
Thus the total number of side is 4.
