Math Help - coplanar forces

1. coplanar forces

im asked in which direction the given particle would move if the 4N force was removed from this diagram
i already solved several problems involving these coplanar forces but here i have no idea where to start
any help?
oh i forgot to say that the angle between the 'horizontal' and the 4.26N force is 20°

The particle is currently in equilibrium under the action of the three forces. So the sum of any two of these forces is equal and opposite to the third force. Therefore, if the 'horizontal-to-the-right' force of 4N is removed, there will be a resultant force on the particle of 4N that is 'horizontal-to-the-left'. The particle will therefore accelerate to the left.
