Need help with this

    # The tension along the string between knots A and B is unknown. There are four distinct equilibrium conditions, each of which should allow you to calculate the magnitude of the unknown tension

    1. the x components for the knot A tensions
    2. the y components for the knot A tensions
    3. the x components for the knot B tensions
    4. the y components for the knot B tensions


    # Find the magnitude of the unknown tension using each condition. Calculate the percent difference (relative difference) between each value and the average. Did you obtain the same results within an acceptable amount of experimental error?

    Equilibrium Data
    Number Mass(g) Tension Angle X component Y Component
    1 350 3.43 48 -2.295 2.549
    2 310 1.568 97 -0.191 1.556
    3 160 2.646 82 0.368 -2.620
    4 270 3.038 42 2.258 -2.033

    please check my math

    tension = mass * 9.8
    x component = tension * cosin angle
    y = tension * sin angle
