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.)

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,

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

answer: t=3

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
