FOUNTAINS Architects who design fountains know that both the height and distance that a water jet will project is dependent on the angle at which the water is aimed. For a given angle , the ratio of the maximum height H of the parabolic arc to the horizontal distance D it travels is given by _ H D = _1 4 tan . Find the value of , to the nearest degree, that will cause the arc to go twice as high as it travels horizontally. 8
