The sun is behind a building and casting a shadow. How long is the shadow if the building is 25 feet tall and the angles, of the shadow, oppsoite the building is 27°? (Assume the bulding is at a right angle to the ground).

A) 0.2ft

B) 55.07ft

C) 28.06ft

D) 59.07ft

Respuesta :

Answer:

Length of shadow = 49.07 feet

Step-by-step explanation:

We have given,

Height of building, AB = 25 feet

Length of shadow be BC.

Angle of the shadow opposite to the building = 27°

Using trigonometric function tan function

tan( 27 ) = [tex]\frac{AB}{BC}[/tex]

or BC = [tex]\frac{AB}{tan(27)}[/tex]

or BC =  49.07 feet

So, length of shadow , BC = 49.07 feet
