Question 4795
hopefully you mean {{{174=180(n-2)/n}}}?


Get rid of the fraction first --> {{{174n=180(n-2)}}}
now multiply out the bracket --> {{{174n=180n-360}}}
now got all n terms together and the others on other side --> {{{6n=360}}}
now divide by 6, to give n=60.


{{{178= 180(n-2)/n}}}
{{{178n= 180(n-2)}}}
{{{178n= 180n-360}}}
{{{2n=360}}}
so n = 360/2
n = 180


hope these help
