An airplane is flying at 4000 feet above the ground. If the angle of depression from the airplane to the beginning of the runway is 5.4°, what is the horizontal distance, to the nearest tenth of a mile, from the airplane to the beginning of the runway?

Answer :

Answer:

42315.6

Step-by-step explanation:

Let the horizontal distance be x.

[tex]\tan 5.4^{\circ}=\frac{4000}{x} \\ \\ x=\frac{4000}{\tan 5.4^{\circ}} \\ \\ x \approx 42315.6[/tex]
