An airplane begins a descent to a sea-level airport at an angle of -4° to the horizon. What is the change in elevation after it flies 10,000 feet horizontally toward the runway if the original horizontal distance was 15000 feet ?

Respuesta :

Using the slope concept, it is found that the change in elevation was of -699 feet.

What is a slope?

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

In this problem, we have that:

  • The vertical change is of h.
  • The horizontal change is of 10,000 feet.
  • The angle is of -4º.

Hence:

tan(-4º) = h/10000

h = 10000 x tan(-4º)

h = -699.
