A 600-ft guy wire is attached to the top of a communications tower. If the wire makes an angle of 75° with the ground, how tall is the communications tower? (Round your answer to the nearest foot.)

Respuesta :

Answer:

580 ft

Step-by-step explanation:

We are given that

Length of guy wire=600 ft

[tex]\theta=75^{\circ}[/tex]

Let h be the height of communication tower.

In triangle ABC ,

[tex]\frac{AB}{AC}=\frac{perpendicular\;side}{hypotenuse}=sin\theta[/tex]

Substitute the values then we get

[tex]\frac{h}{600}=sin75^{\circ}[/tex]

[tex]h=60 sin75^{\circ}[/tex]

[tex]h=579.5ft [/tex]

[tex]h=580 ft[/tex]

Hence, the height of communication tower=580 ft
