Briley Walters · Answer 1

2,712.2 ft

Step-by-step explanation:

Let d = the horizontal distance from Charlie to the plane.

By definition,

tan (32°) = 1694.8/d

1694.8/d = 0.6249

d = 1694.8/0.6249 = 2712.2 ft

Roselyn Murray · Answer 2

2720 feet

Step-by-step explanation:

u can draw a right triangle whose opposite side is 1700 feet, the adjacent side is the ground distance from Charlie to the plane (x), and the angle between theses sides is 32°.

Then, tan (32°) = 1700 feet / x = > x = 1700 feet / tan (32°) = 1700 feet / 0.625 = 2720 feet.
