A line AB cannot be measured directly because of an obstruction on line, Accordingly, the two lines AC and CB were measured as 2,400.850-m and 1,320.420-m, respectively. Point C was set at a perpendicular distance of 155-m from point D on line AB. Using the approximate slope correction formula for steep slopes, determine the length of AB.
