You're riding in an airplane flying at the height of 2 miles above the ground.the distance along the ground from airport is 5 miles.what is the angle of depression from the airplane to the airport

This might be what it looks like.

Since we're dealing with an angle, its opposite side and it's adjacent side, we use TANGENT.

[tex]tan(angle)= \frac{opposite}{adjacent} [/tex]

opposite=5
adjacent=2

By taking the angle, we use inverse.
[tex]angle= tan^{-1} \frac{5}{2} [/tex]

Then we can finally know the value by using your calculator. :)
