Problem 1

To determine the horizontal distance between the tip of a lightning rod atop a smokestack (LR) to the top of a tall flagpole (FP) a surveyor used two instrument setups (1 and 2) and measured the horizontal angles shown on the diagram. She also measured the horizontal distance between the two instrument locations as 552.36 feet.

Using these measurements, what is the horizontal distance from the lightning rod to the flagpole?

Solution: COGO 3 Prob 1
