  1. the rope forms a 2-3-4 triangle , with the longest side parallel to the ceiling

    use the law of cosines to find one of the angles
    ...then use the law of sines to find the other two

    the vertical components of the two tensions (2 and 3)
    ... are equal to the gravitational force on the 10 kg mass

    drawing a force diagram may be helpful
