9. A level is setup midway between two wood stakes that are about 300 feet apart. The rod reading on stake A is 8.72 feet and it is 5.61 feet on stake B. The level is moved to point B and set up so that the eyepiece end of the telescope is touching the rod as it is held plumb on the stake. A reading of 5.42 feet is determined on the rod at stake B by sighting backwards through the telescope. The level is then sighted on the rod held on stake A, where a reading of 8.57 feet is noted. a) What is the correct difference in elevation between stakes A and B? b) If the level had been in perfect adjustment, what reading would have been observed at stake A, from the second setup? c) What is the line of sight error in 300 feet? d) Describe how you would eliminate the line of sight error from the scope:

11. When an alidade and a plane table were set up over a point the elevation of the line of sight of the alidade was 406.29m. In order to determine the elevation of point M, the stepping method was used. The interval intercepted between the stadia hairs on a rod held on M was 1.95m. After the line of sight was depressed for five steps from the horizontal line of sight, the rod reading at the horizontal cross hair was 2.62m. Determine the elevation of point M.

In carrying out the permanent adjustments of a level by, the following observations were made: Instrument at peg (C) midway between points A and B, 100m apart. Readings at points A and B are 2.500m and 3.500m, respectively. Instrument at peg (D) in line of AB such that AD-120m and BD-20m, Readings at points A and B are 1.500m and 2.600m, respectively. Check whether the instrument needs permanent adjustment or not and whether the line of sight is inclined upward or downward. What should be the correct reading at (A and B) if the instrument is to be adjusted?
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?
