Okay I can't seem to think of how to solve this I basically need to have the y force be zero... currently I have 90 + 70 sin(x) - 130 cos(x) = 0 I feel like there is an inverse tan in my future but I can't get there...

This question doesn't make much sense. Do you need to solve this equation for ? If so, do this: Let and Can you complete it from here? Grandad
I'm sorry I realized I mixed and matched problems from my whiteboard.... I actually need to find the tensions on A and B, (I have the angles) so... A*cos(25) + B*cos(40) = -70*cos(10)

A*cos(25) + B*cos(40) = -70*cos(10) Still doesn't make sense! You'll need a second equation in order to solve for A and B. Grandad
