Three forces -- in equilibrium or not?

Hi. I am new to physics and need some help on this question asap. Did I get it right or is it wrong? Correct me if I am wrong. Thank you.

You are correct. It's not in equilibrium left to right but your working should really include the equation that proves it. eg...

33Cos(30) - 20Cos(22) <> 0
