SECTION B Answer TWO of THREE questions Figure B1 shows a line traverse that starts from known stations A and B and finishes at known stations E and F. The clock-wise angles ABC, BCD, CDE and DEF are also known. The azimuth AB is equal to 151° 27' 38" and azimuth EF is 332° 56' 34". Figure B1 (this is just a sketch, lengths and angles not in scale) F A 260°15' 48" 110°03' 40" 141°10' 21" 29°58' 55" E C B (a) Calculate the angular error for this traverse and its adjustment. [15 marks] For the same traverse of Figure B1, calculate the traverse error. Table B1 shows the coordinates of the known stations and the traverse line lengths.
