cfferential leveling, the elevation of a turning point is usually found by: Adding the foresight to the current H.I. Subtracting the foresight from the current H.L Subtracting the backsight from the H.L Adding the backsight to the elevation of the benchmark None of the above A benchmark (B.M.) is a point of known elevation that should remain in place for only one week. TRUE FALSE 18 To obtain the elevation of a furning point, add the level...

9. A survey crew wants to measure the height of a power line. The surveying crew set up a theodolite 138.32 feet from the power line. The surveying crew took the following vertical angle readings: • Angle to a point directly below the power line = 2° 16' 20". • Angle to the lowest point of the bottom conductor of the power line = 21°05' 15". What is the clearance under the power line? (10 points)
