s=180n-360 for n

OpenStudy (lalaly):

(s+360)/180=n

OpenStudy (anonymous):

i dont understand

OpenStudy (lalaly):

first u add 360 to both sides cn u do that?

OpenStudy (anonymous):

yep

OpenStudy (lalaly):

ok so u get s+360 = 180n

OpenStudy (lalaly):

now divide both sides by 180

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

n=s+2?

OpenStudy (lalaly):

n=(s+360)/n

OpenStudy (anonymous):

s + 360 = 180n -360 + 360 s + 360 = 180n 180n = s + 360 just reverse it by writing left to right and right to left n = (s+360)/180

OpenStudy (anonymous):

okay i have 180n divided by 180 equals n, then i have s+360 over 180

OpenStudy (anonymous):

so i divide s and 180 by 180?

OpenStudy (anonymous):

?
