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 $(h)$

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

WINSTONCH [101]

$8 {(x + 8)}^{2} + 9 \geqslant 9 \: ( {(x + 8)}^{2} \geqslant 0) \\ \Leftrightarrow x + 8 = 0\Leftrightarrow x = - 8 \\ \Rightarrow D.\: Minimum\: at\: x=-8$
