(adsbygoogle = window.adsbygoogle || []).push({}); Tension of 2 Ropes are known angle and mass unknown help please

1. The problem statement, all variables and given/known data

A block mass M hangs in equilibrium. A horizontal rope attached to the block has a tension of 30N. Another rope attached to the cieling with a tension of 90N, and makes an angle with the ceiling. What is the angle

2. Relevant equations

I was thinking the inverse tangent

tan = y/x being y= 90 and x = 30

3. The attempt at a solution

inverse tan = 30/90 = 0.3333 18 degrees

i'm probably doing something wrong cause i think gravity here is important i just dont see how to put all this together

Any suggestions or corrections would be helpful
