Distance by Subtense Bar. A subtense bar 2.00 meters long is set up nearthe middle of a traverse line PQ. Using a theodolite set up at P, the anglesubtended reads 0°20' 14'". When the theodolite was transferred and set upat Q, the corresponding subtended angle was observed as 0°23'47'".Determine the horizontal length of line PQ.2.
