Answer 1

Given:

A wire attached to the top of a pole is also attached to a stake in the ground 20 feet from the foot of the pole and makes an angle 22 degree with the pole.

Required:

Find the length of wire?

Step-by-step explanation:

We know the trigonometric ratio of cosine

`Cos\theta=(Base)/(Hypotenuse)`

Now,

`\begin{gathered} Cos22^(\circ)=(20)/(x) \\ 0.93=(20)/(x) \\ x=21.5ft \end{gathered}`

Answer:

Hence, above is the answer.
