Question

3. A pilot in a plane spots a forest fire on the ground at an angle of depression of 54 degrees. The planes altitude is 4,000 feet. What is the horizontal distance from the plane to the fire?

Answer 1

2906 ft

Explanation:

tan = opp/adj

height = opp = 4000

distance = adj

tan 54 = 4000/distance

distance = 4000/tan54

distance = 2906.170112021443544

Rounded

2906 ft
