A closed traverse was run from A to B, then C and back to A, with radiations made at B and C to Y and X respectively. The diagram below shows the reduced observations made at A and B and the field notes recorded when the theodolite was set up at C. When the distances were observed at C, the tape was placed on evenly sloping ground and the appropriate vertical angle observed. Reduce the field notes made at C, in the spaces on the booking sheet. Horizontal Angle ABC observed at B is 65-12-50. Horizontal Angle ABY observed at B is 188-46-00. 18 Horizontal Distance B-C is 28.643 Horizontal Distance B-Y is 4.610 Y Not to Scale NB. Angles are shown in the format ddd mnss REDUCE THESE OBSERVATIONS MADE AT POINT C TO COMPLETE THE TRAVERSE TABLE.
