1.In taping from A to B, a tree on-line necessitated setting an intermediate point C offset 4.5ft to the side of line AB. Line AC was then measured as 368.92ft along a uniform 4% slope. Line CB on horizontal ground was measured as 285.10ft. Find the horizontal length of AB.
2.Compute the corrected horizontal distance for the following conditions: Temperature: 25oC Tape length: 29.990m Slope angle: -3o42’ Slope measurement: 211.416m
