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

Answer:
The angle of descent of Artemis' plane is 6°
Step-by-step 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°
