1. An airplane is flying at constant altitude of 100 m above the ground. At that instant, it
was recorded that the angle of depression of the airport is 40°. Find the horizontal
distance between
the airplane and the airport. Below are the solution of the two physics
student. Observe carefully and figure out the correct answer.​

Answer:

Ely's solution is the correct one

Step-by-step explanation:

use tangent = opposite / adjacent

in this case, angle is 40 degrees which is opposite the vertical side of the triangle that measures 100 m (given). adjacent to the angle is the distance between the airplane and airport (unknown, let this be x)

tan 40 = 100 / x

x = 100 / tan 40
