Question: A closed loop traverse has been established that contains five TBMs ( A - E ) . The stations have been labelled in a clockwise
A closed loop traverse has been established that contains five TBMs AE The stations have been labelled in a clockwise rotation; hence the external included angles were measured when establishing the traverse, and TBM A has the coordinates easting and northing respectively The theoretical angle check indicated a misclosure and the use of the Bowditch method indicates a linear misclosure of in Both of which were deemed acceptable. The Bowditch correction applies a change in easting and northing and respectively to the change in easting and northing calculated and respectively when manipulating the whole circle angles and horizontal distances to determine the coordinates for each TBM within the traverse to produce corrected changes and respectively such that:

The calculation for the coordinates in the traverse was started but not completed. Calculate the easting coordinate value for TBM E by applying the Bowditch correction. Please state the value in metres to three decimal places
