    1. The problem statement, all variables and given/known data
    59 N weight held by two cables. The left-hand cable is horizontal.

    What is the tension in the cable slanted
    at an angle of 51◦? Answer in units of N.

    What is the tension in the horizontal cable?
    Answer in units of N

    Angle 51 wrt to which axis? The horizontal or vertical?

    Remember that the horizontal cable cannot transmit any force in the vertical direction; hence, only the slanted cable upholds the weight.

    Furthermore, since that cable is slanted, it follows it transmits to the weight a force also in the horizontal direction; thus, in order for the weight to remain in equilibrium, the strictly horizontal cable must counteract that force by its own trension.
