    The only difference on paper one was the functions question, they had an exponential graph. :)

    I'm almost sure the swing was 7.4.
    Tan X = 5/4
    X = Tan -1 (5/4)
    X = 51.34

    51.34 * 1.2 = 61.6

    Tan 61.6 = x/4
    4 Tan 61.6 = x
    x = 7.39
    x = 7.4

    Idk if that's right or wrong but how I did it.
