A communications tower is located at the top of a steep hill, as shown. The angle of inclination of the hill is 70°. A guy wire is to be attached to the top of the tower and to the ground, 160 m downhill from the base of the tower. The angle formed by the guy wire is 18°. Find the length of the cable required for the guy wire.

length of guy-wire =  m

Round your answer to the nearest tenth of a meter.

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.

height of a Tower A guy wire is attached to the top of a communications tower. If the wire makes an angle of with the ground, how tall is the communications tower?

Calculating an Angle: A water tower tall is located at the top of a hill. From a distance of down the hill it is observed that the angle formed between the top and base of the tower is . Find the angle of inclination of the hill.
