Determine the ground clearance of an overhead electrical cable.surveyor B is positioned directly under the cable(surveyor B's position can be checked by his sighting past thesting of a plumb bob,held in his outstreched hand, to thecable);surveyor A sets her clino meter 45 degree and then backs away from surveyor B until the overhead electrical cable is on the cross hair of the leveled clinometer.at this point, surveyors A and B determine the distance between them to be 61.5 ft .surveyor A then sets the clinometer to 0 degree and sights surveyor B ; this horizantal line of sight cuts surveyor B at a distance 4.3 ft above the ground . Determine the ground clearance of the electrical cable.
