5. A line AB cannot be measured directly because of an obstruction on line. Accordingly, the two lines AC and CB were measured as 2704.06 m and 1518.40 m, respectively. Point C was set at a perpendicular distance of 109.850 m from point D in line AB. Using the approximate slope correction formula for steep slopes, determine the length of AB. Obstruction- A D dz
