Charlie is at a small Airfield watching for the approach of a small plane with engine trouble he sees a plane at an angle of elevation of 32 at the same time the pilot radius radios Charlie and reports a plane's altitude is 1700 ft Charlie's eyes are 5.2 ft from the ground find the ground distance from from Charlie to the plane show how you know

    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

    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.
