The tallest free-standing tower in the world is the CN Tower in Toronto, Canada. The tower includes a rotating restaurant high a

tatiyna

Answer:

(a)1815 feet

(b)665 feet

Step-by-step explanation:

(a)From the diagram, we want to determine the height CN of the tower.

$Tan \theta =\frac{Opposite}{Adjacent} \\Tan 74.6 =\frac{|CN|}{500} \\|CN|=500 X Tan 74.6=1815.24 feet$

The CN tower is 1815 feet tall.

(b)To determine how far below the pinnacle of the tower the restaurant is located. We are to determine the distance RN.

|CR|+|RN|=|CN|

First, we determine |CR|

$Tan \theta =\frac{Opposite}{Adjacent} \\Tan 66.5 =\frac{|CR|}{500} \\|CR|=500 X Tan 66.5=1149.92 feet$

|CR|+|RN|=|CN|

|RN|=|CN|-|CR|=1815-1150=665 feet

The restaurant is located 665 feet below the pinnacle of the tower.
