Question

An airplane is flying at an altitude of 2.7 miles and is 8.3 miles from the runway. Find the angle of depression from the airplane to the runway

Answer 1

Explanation:

AB = altitude = 2.7 miles

BC = 8.3 miles

`\sf tan \ \theta = (opposite \ side \ of \ \theta)/(adjacent \ side \ of \ \theta)\\\\Tan \ \theta = (AB)/(BC)=(2.7)/(8.3)\\\\Tan \ \theta = 0.33\\\\\theta = tan^(-1) \ 0.33`

`\boxed{\theta = 18.3}`
