Question

An airplane flying at an altitude of 7,000 feet is 5 miles from the runway where the pilot plans to land. To the nearest degree, what angle of depression should the plane assume? (Use 5,280 feet = 1 mile)

Answer 1

Altitude is the opposite side, 5 miles is the adjacent side of a triangle with right angle directly under the plane, on the ground. We use tangent. Also, 5 miles is 5*5280 = 26400 feet

Answer 2

Okay thank you
