Question: What is the average zenith angle given the following direct and reversed readings? Direct: 94o 23' 48'', 94 o 23' 42'', 94 o 23' 44''

What is the average zenith angle given the following direct and reversed readings?
Direct: 94o 23' 48'', 94 o 23' 42'', 94 o 23' 44''
Reversed: 265 o 36' 20'', 265 o 36' 24'', 265 o 36' 22''
In Figure 8.9(c), direct and reversed directions observed with a total station instrument from A to points B, C, and D are listed in Problems 8.23 and 8.24. Determine the values of the three angles, and the horizon misclosure.
