Two guy wires are attached to the top of a radio tower on the same side. The angle from
the ground made by the first guy wire is 65º. Twenty feet closer to the tower (and in the
same plane as before), a second guy wire makes a 75° angle with the ground. How tall is
the tower? Round to the nearest foot.
