Question

the angle of depression from a plane to the airport is 34°. the pilot reports that the plane's altitude is 3200 feet . find the horizontal distance between the plane and the airport to the nearest foot

Answer 1

$look\ at\ the\ picture\\\\cot34^o=\frac{x}{3200}\\\\cot34^o\approx1.4826\\\\\frac{x}{3200}=1.4826\ \ \ \ /\cdot3200\\\\x=4744.32\ (ft.)\approx4744\ (ft.)\leftarrow answer$
