Respuesta :

Answer:

≈ 27 ft

Step-by-step explanation:

using the tangent ratio in the right triangle formed by the building and the ground.

tan15° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{?}{100}[/tex] ( multiply both sides by 100 )

100 × tan15° = ? , then

? ≈ 27 ft ( to the nearest whole number )
