This Problem is Now Closed
Trees’ A Crowd
Since the last problem may have been a bit too much a challenge, we’ll try something a little simpler.
Two adjacent property corners, A and B, are not intervisible due to trees. The surveyor set two other points, C and D, and measured the angles and distances at them as shown on the diagram.
What is the distance between A and B? Determine to 0.01 ft.
