The height of the radio tower is 327.3070 feet.

Step-by-step explanation

Let's first sketch the problem.

From the sketch above, adjacent = 46 θ=82

opposite = h (height of the radio tower.

Using the trigonometric ratio,


\tan \theta=\frac{\text{opposite}}{\text{adjacent}}


\tan 82=(h)/(46)

Cross-multiply


h=46*\tan 82

h ≈ 327.3070 feet.

Therefore, the height of the radio tower is 327.3070 feet.
