2. It is desire to measure angle AOB with the transit at 0, but due to the fact that 0 is a swamp, the transit is set up at C which is 10 m., from 0 and the angle ACB was measure. If angle ACB is 60° and AC = CB = 200 m., and OCA = 90°, find the value of angle AOB. 3. In measuring the angles at a triangulation station 0, it was necessary to set the transit over another point T at a distance of 13.25 ft. from 0. The angle measured at T from 0 to the first distance "W" was 95°10' 30". The angles between the distant stations W, X, Y and Z were as follows: WTX = 39°37'48", XTY = 69°04' 20", YTZ = 83°16' 08". The distance to the stations are found to be OW = 8949 ft., OX = 14334 ft., OY = 5647 ft. and OZ = 7326 ft. Correct the angles measured at station T to those which would have been measured if the transit has been set at station 0, that is solve for the angle wox. 4. The angles between stations A and B is measured from station B and found to be 71°10' 10.5". The angle from 0; to the right, to station A is 110°15'. The distance OE is 7.46 m. OA is 17650 m. and OB is 24814 m. Reduce the angle to center 0 that is solve for angle AOB.
