Respuesta :

For this case, the first thing to do is find the horizontal distance from the plane to the zoo and the library respectively.
 We then have the following trigonometric relationships:
 For the zoo:
 [tex] tan (60) = (300 * root (3)) / d1 [/tex] 
 Clearing d1 we have:
 [tex]d1 = (300 * root (3)) / tan (60) d1 = 300[/tex]
 For the library:
 [tex] tan (30) = (300 * root (3)) / d2 [/tex] 
 Clearing d1 we have:
 [tex] d2 = (300 * root (3)) / tan (30) d2 = 900[/tex]
 Then, the distance between zoo and library is:
 [tex] d2 - d1 = 900 - 300 d2 - d1 = 600 feet[/tex]
 Answer:
 
The distance between the zoo and the library is:
 
600 feet

600 feet is your answer
