Re: find a b c

well as youve said

a +2b + 2c = 360
a = b + c

so substitute that and you get an equation

3b + 3c = 360, or b + c = 120

then you have b = c

so substitute that into the equation, and you get 2c = 120, or c = 60.

with c = 60, you then have b = 60, and therefore a = 60+60 = 120.

a:120, b:60, c:60
