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°

Lunna [17]

Answer and Step-by-step explanation:

$x=2$

→ Step 1: Subtract 7 from both sides :

$-3x+7-7=1-7$

$-3x=-6$

→ Step 2: Divide both sides by -3:

I don't have a calculator on me currently, but what you would do is multiply 9X9X9, then the product of that would be added to the product of 10X12X16, so (9X9X9)+(10X12X16)=the total volume.
