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.

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
