1. A tachometric surveying was conducted to obtain some readings for inaccessible points, where it was found that the multiplying and additive constants are 98 and 0.1, respectively. The instrument was setup at point C and the readings listed in the table were taken while the staff was held vertically. Calculate the horizontal distance between BM and station D. Also, calculate the reduced level of station D. Figure 1 shows a schematic view of the site. 2.
