Problema Solution
a pilot flying at an altitude of 12,000 ft sights two airports directly in front of him. The angle of depression to one is 78 degrees, and the angle of depression to the second airport is 19 degrees. what is the distance between the two airports? round to the nearest foot.
Answer provided by our tutors
make a good drawing and the trigonometric function tan
the distance d = 12000 * tan 78 - 12000 * tan 19
d = 12000(tan 78 - tan 19)
d = 52,323.6308 ft
d = 52,324 ft
