Hello guys,
Long time no see.
I made this thread for anyone who wants any advise on these subject as I have been learning a big understanding of those.
I've currently joined a college doing Science Engineering and this is the best place I thought of where I would get the best advice.
My current problem is this:
The longest side of a triangle has the length (2x1) cm. The other sides have the lengths (x1) cm and (x+1) cm. Given that the largest angle is 120/degrees, work out :
a) The values of x b) The area of the triangle
I figured that the first is to use quadratics and the cosine law and the second uses 1/2absin(C) (which I'm okay with, it's mostly the first question).
Thanks for anyone who can help.
 Nicky

Hi Nicky, is this a homework question. :) Your best place to get an accurate answer might be a site like Mathematics Stack Exchange.

No it wasn't a home work question, it was some revision I was doing:) but thanks for the website, I manage to pass my first test (algebra) second test is now calculus.
