    here's a clue ...

    \sum{F_x} = 0

    \sum{F_y} = 0

    sketch a diagram of the forces acting on the hanging mass and come up with a pair of equations reflecting the condition of static equilibrium in the x and y directions.

    in the x-direction ...

    force component left = force component right

    T\cos{\theta} = 4

    solve for T

    in the y-direction ...

    forces up = forces down

    T + T\sin{\theta} = Mg
