    range of object projected at an angle θ

    R = (V²/g)sin(2θ)

    V is initial velocity in m/s

    g is the acceleration of gravity 9.8 m/s²

    300 = (V²/g)sin(2•30) = (V²/g)sin(60)

    basically what angle has the same value for the sine as 60º and that is 120º, and half that is 60º

    By symmetry, it would be 60 degrees.
