A tower 28.4 feet high, must be secured with a guy wire anchored 5 feet from the base of the tower. What angle will the guy wire make with the ground?

Securing a Tower: A tower is located on the side of a mountain that is inclined to the horizontal. A guy wire is to be attached to the top of the tower and anchored at a point downhill from the base of the tower. Find the shortest length of the wire needed.

Radio Antenna: A short-wave radio antenna is supported by two guy wires, and long. Each wire is attached to the top of the antenna and anchored to the ground at two anchor points on opposite sides of antenna. The shorter wire makes an angle of with the ground. How far apart the anchor points?

Length of a Guy Wire: A communications tower is located at the top of a steep hill. The angle of inclination is . A guy wire is to be attached to the top of the tower and to the ground, downhill from the base of tower. The angle in the figure is determine to be . Find the length of the cable required for the guy wire.
