Question

3. A telephone pole is supported by two wires on opposite sides. At the top of the pole, the wires
form an angle of 55º. On the ground, the ends of the wires are 11.0 m apart. One wire makes a
(4) 41° angle with the ground.
a) How long is each wire? (round to the nearest tenth)
b) How tall is the pole? (round to the nearest tenth)


I understand A, but please help with B asap!!!!!

Answer 1

Answer: 1.044 meters

Explanation:

Since the angle of one wire to the ground is 41 degrees, and the bottom of the pole to a wire is 6.5 m (11.0 / 2), we can use trignometry to find it.

tan 41 = opposite (pole) / 6.5 (the length of the wire to the pole on the ground)

pole = tan 41 *6.5

pole = 1.044 meters
