(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Weight suspended by 3 cords. 1 from the weight goes up vertically to the knot. The next goes left 30°belowhorizontal and the last goes to the right 45° above horizontal.

2. Relevant equations

f=ma

3. The attempt at a solution

I dont think I've ever worked a problem with a cord below horizontal. So I'm stumbling a bit.

Since there's only 1 cord above horizontal (T_{1}) it should carry the whole y force. So, in y T_{1}=T_{2}+T_{3}

And, in x the left and right cords must be equal T_{1}=T_{2}

T_{1}sin(45)=T_{2}sin(30)+mg

Not sure about the rest. Any help?
