Answer the subquestions: A. A slope measurement of 545.38 m is made between points A and B. The elevation of A is 424.25 m and that of B is 459.06 m. Determine the horizontal distance between two points. B. A traverse line was measured in three sections: 295.85 m at slope 8°45’, 149.58 m at 4°29’, and 373.48 m at slope 4°23’. Determine the horizontal length of the line. Note: Draw the figure and show the complete solution. Provide a recheck of the answers.
Situation No. 1: The baseline AB of a triangulation systemis equal to 400m. long. Station C and D are other points of the triangulation system. The angles observed from A and B are as follows. Angle DAB = 27° 30', angles CAB = 78°30', angle CBA = 52° and angle DBC 30°30' 1.) Compute the Distance CB 2.) Compute the Distance DB 3.) Comoute the Distance DC 4.) Find the area of each triangle and the total area Situation No. 2: A and B are two points located on cach bank of a river and near the abutments of a proposed bridge. To determine its distance, a baseline CD 180m long was established on one bank of the river and the transit was set up at station C and D and the azimuth were taken as follows. Line С -D Azimuth 1.) Find the distance AD 2.) Find the distance BD 3.) Find the distnace AB 4.) Find the area of each triangle and the total area 210° 00' C-A 260° 00' С -В 290° 00' D- A 301° 00' D- B 315° 00'
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…
