Refer to the diagram shown below.
Let d =  the horizontal distance from Charlie to the plane.
By definition,
tan(32°) = 1694.8/d 
1694.8/d = 0.6249
d = 1694.8/0.6249 = 2712.2 ft
Answer:  2,712.2 ft
 
        
        
        
Sometimes it helps to put a number line in front of you. If one number is to the left of the other number on the number line, it's a lower number. If one number is to the right of the other number on the number line, it is greater. 
-5 -4 -3 -2 -1 0 1 2 3 4 5
4 is a solution of x<-5
FALSE: 4 is not greater than -5
-3 is a solution of y>-2
FALSE: -3 is not greater than -2
y≤3 includes 3 as a possible solution
TRUE: 3 is less than OR EQUAL to 3
Hope this helps! :)
