kotegsom [21]

Answer:

  • 52.35 m

Step-by-step explanation:

<em>Refer to picture.</em>

Let the distance to men are x and y and the distance between them is d.

The angle of depreciation is 27° and 30°, hence top angle of the triangle is 63° or 60°.

<u>Find the distance from the tower to men:</u>

  • x = 20 tan 63° = 39.25 m
  • y = 20 tan 60° = 34.64 m

<u>The distance between men is:</u>

  • d = \sqrt{x^2+y^2} =\sqrt{39.25^2+34.64^2} = 52.35m

<em>Note, all numbers are rounded</em>

I believe that in this problem, we are asked for the hypotenuse of the triangle that can be formed when we make a right triangle out of the planes and the intersection of their paths. To solve for the hypotenuse of a right triangle, we make use of the equation,
                                   h² = 64.2² + 85.7²
The value of h from the equation is equal to 106.0 miles.
