The question is this:

From a position 275 m above the earth, a man in a tower observes two landmarks on level ground. He finds their angles of depression to be 38 and 46 degrees and the angle subtended by his lines of sight to be 59 degrees. Find the distance between the landmarks.
I can't seem to get the right sketch, or a sketch that makes sense. If the subtended angle is 59, then shouldn't one angle of depression - second angle of depression = 59 degrees? Solving it isn't the problem, it's just getting the right sketch.

Any help is appreciated.
