Two guy wires are attached to the top of a radio tower. The wires are 75 ft. and 52 ft. long. The
longer wire is anchored to the ground at a point 58 ft. from the base of the tower. The shorter wire
is anchored to the ground at a point between the base of the tower and the longer wire. Calculate
the angle of inclination of the shorter guy wire to the nearest tenth of a degree.
