Answer 3

The angles don't add to 360 (you're thinking of quadrilaterals)

Answer 4

S = 180(n-2)

S = 180(5-2) ... 5 sides ---> n = 5

S = 540

The angles add to 540

Answer 5

oh so so then my answer would be...540-100-160-95-115 and ill get my answer

Answer 6

which would be 70

Answer 7

yeah you start off with 100+160+95+115+x = 540 and you solve for x like that

Answer 8

x = 70 is right

Answer 9

okay thank!
