An airplane is flying at an altitude of approximately 2 miles above ground level. The pilot sights a landmark at an angle of depression of 11°. One minute later, the pilot sights the same landmark at an angle of depression of 18°. To the nearest tenth of a mile, how far did the plane fly in that minute?

0.3 miles

Step-by-step explanation:

Using Trigonometry ;

Height, h = 2 miles

First sighting :  

Horizontal distance h1 ;

h1 = 2tanθ

θ = 11°

h1 = 2 * 0.1943803

h1 = 0.3887606 miles

Second sighting ;

Horizontal distance h2 ;

h2 = 2tanθ

θ = 18°

h2 = 2 * 0.3249196

h2 = 0.6498393 miles

Horizontal difference :

0.6498393 miles - 0.3887606 miles

= 0.2610787 miles

= 0.3 miles

based on context clues you gave i'm assuming the answer would be c.

yes
