Question

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

Answer 1

1.49

Explanation:

Answer 2

`Height\approx 1.35\ miles`

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=(opposite)/(hypotenuse)\\\\\sin 25=(h)/(3.2)\\\\h=3.2* \sin 25\\\\h=3.2* 0.4226\\\\h=1.3524\approx 1.35\ miles`
