Please complete and submit with your script Question 2 Your colleague has carried out a traverse and has given you the part completed results shown below in Table Q2.1 (overleaf) a) Complete Table Q2.1 and calculate the coordinates of the stations using the Bowditch method, given that the coordinates of the station A are 150.000E and 150.000N. [16 marks] b) At point X, there is an existing manhole (MHX). Its invert level is 100.650m AOD. A new manhole is to be constructed to MH1. The coordinates of the existing and new manholes are provided as MH1 (900.000E, 1000.000N) and MHX (850.000E, 850.000N). Using Pythagoras and the given coordinates of the stations, compute the distance of MH1 to MHX. Support your answer with a sketch showing the locations of the existing and proposed manholes. and the distance between them.
