    Use the definition of tangent

    or inv tangent (arctan or atan)

    tan (theta) = opposite side / adjacent side

    the vertical rise would be the opposite side, the horozontal distance would be the adjacent side

    let rise = y

    let distance = x

    x=2y

    so tan (theta) = y/2y

    tan (theta) = 1/2

    theta = atan (1/2)

    grab a handy dandy calculator, unless you know this conversion off the top of your head
