HELLO PLEASE HELP, WITH COMPLETE SOLUTION. PLEASE DO NOT MAKE IT COMPLICATED THANK YOUU! 4 DECIMAL PLACESS
A theodolite was set up at station A and its height of set up was taken as 2.22m. A stadia rod held at point B was observed at a rod reading of 3.20m with its line of sight on a horizontal position. The elevation of point A is 305.56m. Determine the elevation at point B. Select the correct response: 305.67m 304.58m 309.34m 307.56m
What is the correct rod reading at A with the instrument set up at B? Refer to Table 3.
Calculate the value of degree of static indeterminacy
need help.
Three points on the ground were established such that point C is the point where the theodolite was set. A subtense bar were sighted at point A to be 00°18' and at point B is 00°19'30". If the horizontal angle was read between points A and B to be 38°45', find the distance AB. ps. please i need answer ASAP?
11 A theodolite was set up near the middle of the points "P" and "Q". If the height of the instrument is 1.20 m. The rod is sighted at point "P", vertical angle = +24 degrees, rod reading = 1.3 m, and stadia interval = 1.4 m. Then the rod is sighted at point "Q", vertical angle = +23 degrees, rod reading = 1.6 m, and stadia interval = 1.1 m. Taking K = 100, and C = 0. c) Elevation of Point "P" from the base of the theodolite. 51.920 m 32.763 m 44.895 m 41.045 m 48.526 m None of the Choices 36.994 m
