A plane is approaching an aircraft carrier at 25° angle of elevation from 3.2 miles away how far above sea level is the plane

s2008m [1.1K]

Answer:

$Height\approx 1.35\ miles$

Step-by-step explanation:

The angle of elevation $=25\textdegree$

It is $3.2\ miles$ away from the point.

If we imagine a right triangle having an angle $25\textdegree$ .

Hypotenuse $=3.2$ , Opposite=Height from sea level $(h)$

$\sin 25=\frac{opposite}{hypotenuse}\\\\\sin 25=\frac{h}{3.2}\\\\h=3.2\times \sin 25\\\\h=3.2\times 0.4226\\\\h=1.3524\approx 1.35\ miles$

MrRissso [65]

Total = 16
Graduates = 4

$\frac{4}{16} = \frac{1}{4}$
$\frac{1}{4} \div 4 \\ = \frac{1}{4} \times \frac{1}{4} \\ = \frac{1}{16}$
$\frac{1}{16} = 0.0625$
Rounding off to 2 decimal places,
Answer is 0.06
