I have been stuck on this problem for the last half, and to be honest I don't even no where to begin. I'm being asked to calculate all of tensions for the cords. I know I'm supposed to use $\cos$ to calculate the $x$ tensions and $\sin$ to calculate the $y$ tensions, but that's about as far as I'm getting. Can someone please walk me through this and help me understand problem 51?
