Question

A wooden pole is 20 m high. A steel wire is tied to the top of the pole and fixed to the ground. If the angle made by the
wire with the ground is 60°, find the length of the steel wire.​

Answer 1

Answer:

23.09 meters.

Step-by-step explanation:

Sin(60) = opposite / hypotenuse =  pole / steel wire

pole = 20 m

angle = 60 degrees.

sin(60) = 20/ hypotenuse       multiply both sides by the hypotenuse

hypotenuse * sin(60) = 20      divide by sin(60)

hypotenuse = 20 / 0.866        do the division    

hypotenuse = 23.09

The steel wire = 23.09 meters.
