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?
Explanation:
We know the trigonometric ratio of cosine
[tex]Cos\theta=\frac{Base}{Hypotenuse}[/tex]
Now,
[tex]\begin{gathered} Cos22^{\circ}=\frac{20}{x} \\ 0.93=\frac{20}{x} \\ x=21.5ft \end{gathered}[/tex]
Answer:
Hence, above is the answer.
