Problema Solution
A plane is flying at an altitude of 25,000 m. From the pilot, the angle of depression to the airport tower is 30°. How far is the tower from a point directly beneath the plane? Round your answer to the nearest tenth.
Answer provided by our tutors
let d = the distance from a point directly beneath the plane to the airport
d = 25000/(tan 30)
d = 25000/(1/√3)
d = 25000(√3)
d = 43,301.3 m
