Answer:
Base length of plane from control tower = 73,880 feet (Approx.)
Step-by-step explanation:
Given:
Height of plane from ground = 20,000 feet
Height of control tower = 200 feet
Angle of elevation from control tower = 15°
Find:
Base length of plane from control tower
Computation:
Height of plane from control tower = 20,000 - 200
Height of plane from control tower = 19,800 feet
Tan θ = Perpendicular / Base
Tan15 = 19,800 / Base length of plane from control tower
0.268 = 19,800 / Base length of plane from control tower
Base length of plane from control tower = 73,880 feet (Approx.)
