Question

As Artemis Fowl's private jet approaches Heathrow airport, its horizontal distance from the airport is 22 miles when his altitude is 2.2 miles. To the nearest degree, what is the angle of descent of Artemis' plane?​

Answer 1

The angle of descent of Artemis' plane is 6°

Explanation:

Answer 2

The angle of descent of Artemis' plane is 6°

Explanation:

Let

x -----> the angle of descent of Artemis' plane

we know that

The tangent of angle x is equal to divide the opposite side to angle x (altitude) by the adjacent side to angle x (horizontal distance)

see the attached figure to better understand the problem

so

tan(x)=2.2/22

x=arctan(2.2/22)=5.71°

Round to the nearest degree

x=6°
