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 ) = $\frac{AB}{BC}$

or BC = $\frac{AB}{tan(27)}$

or BC = 49.07 feet

So, length of shadow , BC = 49.07 feet
