Answer 2

awh,
good question.

remember this equation:
(n-2)*180 = sum of interrior angles?
this time we know that the sum = 540, so we need to solve for 'n' this time

Answer 3

so subtract 180 on both sides, or divide? thats where im stuck

Answer 4

i divided and added two to both sides and got 5. is that correct?

Answer 5

"so subtract 180 on both sides, or divide? thats where im stuck"

the 180 is times, so we have to divide both sides by 180,
great question ^_^

Answer 6

(n-2)*180 = 540
(n-2)*180/180 = 540/180
(n-2) = 540/180
n-2 = 540/180
n-2 +2 = (540/180) +2
n = (540/180) +2

Answer 7

5 is what i got. and BTW thank you so much you've been a huge help because you actually are helping me understand, not just giving me answers. i appreciate that

Answer 8

yep, 5 is right,
