**bobpursley**, Tuesday, April 6, 2010 at 9:09pmAngle of depression is not enough, what azimuth bearings are they at? Maybe you mean at the same bearing...

draw the figure, let x be the distance apart, h the height of plane, a the distance from the close town to just below airplane.

h/a=tan52

h/(x+a)=tan30

You know h.

first equation, solve for a.

Put that in the second equation, solve for x.
