Answer:

7949.13 feet

Step-by-step explanation:

We are given that,

Angle of depression from the spot to the group = 39°

Height of Grand Canyon = 5000 feet.

So, we will get the following figure of a right triangle.

<em>As, 'in a right triangle, the angles and the sides can be written in trigonometric form'.</em>

We get, \sin A=\frac{perpendicular}{hypotenuse}

i.e. \sin 39=\frac{5000}{x}

i.e. x=\frac{5000}{\sin 39}

i.e. x=\frac{5000}{0.629}

i.e. x = 7949.13 feet

Thus, the line of sight distance is 7949.13 feet.
