1)i)Given A,B and C are angles of a triangle and:
TanA/5 = TanB/6 = TanC/7 = k, show that k= Square-root of 3/35

ii) Hence calculate the smallest of the angles to the nearest minute.

I'm kind of lost in this question, any help would be great thanks!

i realised that evaluating tan(pi/18) is way out of the scope of the extension course but seriously, i thought the denominators were in the brackets. This makes such a huge difference.....
