    I tried to solve it by resolving in the opposite direction of the tensions...this seems to give me wrong answers!Name:  IMG_20160607_170821.jpg

    I think maybe its due to the fact that there is a component of the other tension in each direction that i resolved. Am i right? If thats the case then this type of resolution would be possible only if the tensions were 90 degrees to each other i think.

    Just find the horizontal and vertical components of the forces and then work from there

    If it's held in equilibrium you know 2 things:
    Up = down
    Left = right

    Find the vertical components of all the forces to find an equation with two unknowns (the Tensions).

    Find the horizontal components of all the forces to find an equation with two unknowns (also the Tensions).

    Solve simultaneously.
