When a 757 passenger jet begins its descent to the Ronald Reagan National Airport in Washington, D.C., it is 3900 feet from the

Svetradugi [14.3K]

Answer:

Option A. 37106 ft.

Step-by-step explanation:

Given: An 757 passenger jet at the height of 3900 feet from the ground means vertical height = 3900 feet.

Angle of descent to the airport in Washington,D.C. is 6 degrees.

To find: Horizontal distance the plane will cover to reach the run way.

Solution: As we know tan ∅ = $\frac{Height}{Base}$

Then tan 6° = $\frac{3900}{x}$

0.105 = $\frac{3900}{x}$

x = $\frac{3900}{.105}$

x = 37106 ft
