Q. A Survey line ABDE intersects a building between Band D. To overcome the obstacle a perpendicular BC 90 m long, is set out at B. From C, two lines CD and CE are set out at angles 45º and 60 respectively with CB. Find the lengths CD and CE such that points D and E fall on the prolongation of line AB. Also find the obstructed distance BD.
