A 650-ft guy wire is attached to the top of a communications tower. If the wire makes an angle of 70° with the ground, how tall is the communications tower? (Round your answer to the nearest foot.)

Respuesta :

Answer:

The height of the tower would be 610.80 feet.

Step-by-step explanation:

Consider h be the height( in ft )  of the communications tower,

Given,

Length of the wire = 650 ft,

Angle made by the wire to the ground = 70°

Thus, we make a triangle with sides h and 650 with angle 70°  opposite to the side measures h, ( shown below )

Using trigonometric ratio,

[tex]\sin 70^{\circ}=\frac{h}{650}[/tex]

[tex]\implies h = 650\times \sin 70^{\circ}\approx 610.80[/tex]

Hence, the height of the tower would be 610.80 feet.

The height of the tower would be 610.80 feet.

Given that,

  • A 650-ft guy wire is attached to the top of a communications tower.
  • The wire makes an angle of 70° with the ground.
  • Here we assume h be the height.

Based on the above information, the calculation is as follows:

[tex]sin 70^{\circ} = h \div 650[/tex]

h = 610.80

Therefore we can conclude that The height of the tower would be 610.80 feet.
