When she is 100 feet from the Empire State Building, she looks up at an angle of elevation of 73° and sees a window washer hanging on the side of the building. Sally’s eyes are 5 feet above the street. To the nearest foot, how high is the window washer above the street?

Answer :

Answer:

332.08 feet

Step-by-step explanation:

Let h be the height of the window washer above the street

Using trigonometric ratio

[tex]\tan 73^\circ=\dfrac{h}{100}\\ h=100 \times \tan 73^\circ\\h=327.08$ feet[/tex]

The distance of the window washer above the street

=332.08 feet

The window washer is 332.08 feet above the street.
