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
