    What are all the forces (magnitude and direction) acting on the top of the pole when it's under maximum load?
    What are their components in the vertical direction?

    What haruspex said. Work out what each wire contributes to the vertical load on the pole. As all wires have same tension and geometry the total load is three times that.

    It might help to remember that..

    Cos(θ) = Adjacent/hypotenuse
    = Adjacent/√(Adjacent2+Oposite2)
