Question

Kurt is flying his airplane over a

campground. He spots a small fire below at
an angle of depression of 32°. If the
horizontal distance from Kurt's plane to the
fire is 3600 feet, find the approximate
altitude of his plane.
A. 2,250
B. 2,575
C. 2,825
D. 3,150

Answer 1

5761

Explanation:

Using trigonometry to solve the question which has been represented by the attached triangle :

To obtain the value of h, altitude of airplane ;

Tan x = opposite /Adjacent

Tan 32 = 3600 / h

h = 3600 / tan 32

h = 3600 / 0.6248693

h = 5761.2043
