A helicopter takes off from the ground 800 feet from the base of a building. It flies in a straight line directly to the top of

Stolb23 [73]

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°
