Extracted text: The baseline AB of a triangulation system is equal to 400 m long. Stations C and D are other points of the triangulation system. The angles observed from A and B are as follows: Angle DAB = 27°30', Angle CAB = 78°30', CBA = 52°, and Angle DBC = 30°30. 49 30 70 51° 30°30' 52 27 30' B 400m 78°30' 82'30' Compute the distance CB O 551.47 m O 555.47 m O 511.47 m O 515.47 m
