Work out the coordinates at each station using the traversing method. Check angular and distance misclosure errors. Distribute angular and distance errors if they are within the allowable range.
please help me to solve the calculations of cooridates of A B C D E
As shown in Figure 1, the site covers the surrounding area of building on the north campus. Several control stations have been set and the measurement of horizontal distances and angles have been applied and recorded. The route is counter-clockwise: KZ-7→A⇒B⇒C⇒D⇒E⇒KZ-7, which forms a closed loop. 83°14'28" 100.2 KZ-7 103°0'29" E B 52.9m 26.3m D 51.6m 89°13'40" 81°14'57" Figure 1.
