Cathedral Hill is on a line between Constable Hill and Aurora Hill. Cathedral Hill is 6.235 km from the Constable Hill and Aurora Hill is 11.018 km from the Constable Hill. The elevation of the hills are: Constable Hill, 1260.86 m; Aurora Hill, 1266.44 m; and Cathedral Hill, 1261.04 m. Determine the height of tower to be constructed on Constable Hill so that the line of sight will clear the ground at Cathedral Hill by 5.0 m, if no tower is to be constructed on Aurora Hill
