Exercise: The figure beside it shows the baseline AB with three unknown points and their measurements of distance and angle. If the baseline AB station coordinates are given in the table below, then: Calculate the baseline AB forward and reverse Azimuths, and B the horizontal coordinates of points C, D and E. Notice: The starting baseline Azimuth of C and D is different from the starting baseline Azimuth of E. The horizontal angles should be in clockwise direction always, and the azimuth value ranges between 0 and 400 grads.
