A plane flying at an altitude of 4 miles is approaching an airport that is 31 miles ahead on the pilot's line of sight. What is the angle of depression from the plane to the airport to the

nearest TENTH of a degree?

Step-by-step explanation:

Altitude of the plane = 4 miles

Distance from the plane to the airport = 31 miles

Let the angle of depression from the plane to the airport be represented by θ. Thus applying the appropriate trigonometric function, we have;

Tan θ =

          =

          = 0.1290

θ = 0.1290

  = 7.3506

θ =

The angle of depression from the plane to the airport is .

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
