Ex8-1 During measurement of distance, a pond had been come across the path. Let P and Q are the stations selected on the opposite side of the pond. A line PC = 900 m, was set out on one side of PQ, and a line PD =1100m was set out on the other side, such that CQD was in a straight line. The length of the lines CQ and QD are 500m and 600m respectively. Determine the desired distance PQ.
