Question

Nevaeh spots an airplane on radar that is currently approaching in a straight line, and

Answer 1

Using the slope concept, it is found that the distance the plane traveled from point A to point B was of 18052.4 ft.

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.

At point A, the vertical change is of 7475 ft, with an angle of 16º, hence the equation below can be solved to find the position:

$\tan{16^\circ} = \frac{7475}{x_A}$

$x_A = \frac{7475}{\tan{16^\circ}}$

$x_A = 26068.4$

At point B, the angle is of 43º, hence:

$\tan{43^\circ} = \frac{7475}{x_B}$

$x_B = \frac{7475}{\tan{43^\circ}}$

$x_B = 8016$

Hence, the distance in feet is given by:

$d = x_A - x_B = 26068.4 - 8016 = 18052.4$
