Answer:

11.3°

Step-by-step explanation:

Refer the attached figure .

Height of building i.e. AB = 160 feet.

A helicopter takes off from the ground 800 feet from the base of a building i.e. BC = 800 ft.

We are required to find what angle did the helicopter take off from i.e. ∠ACB

We will use trigonometric ratio .

tan\theta = \frac{Perpendicular}{Base}

tan\theta = \frac{AB}{BC}

tan\theta = \frac{160}{800}

tan\theta = \frac{1}{5}

tan\theta = 0.2

\theta =tan^{-1} 0.2

\theta =11.3^{\circ}

Thus the  angle at which  the helicopter take off from is 11.3°
