Answer:
Distance between the person and the plane is 12 miles
Step-by-step explanation:
From the figure attached,
An airplane is flying at an altitude AB = 6 miles.
An observer is standing at point C from where he observes the plane at an angle of elevation θ
Therefore, sinθ = 
sinθ = 
AC = 
AC = 6cosecθ
If angle θ = 30°
Then AC = 6cosec30
AC = 6×2
AC = 12 miles
Therefore, distance between the person and the plane is 12 miles.

Answer:
57.2 ft
Step-by-step explanation:
The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(G) = IG/GH
GH = IG/cos(G) = (57 ft)/cos(5°)
GH ≈ 57.2 ft
