6) The top(T) of a radio transmission tower was sighted from two small hill tops A and B which were in line with T. the angle of elevation from A to the top of tower was 38°21' and that from B to the top of tower was 21°18'. The angle of elevation from B to a target 3 m above the ground level at A was 14°56', The heights of the theodolite at A and B were 1.80 m and 1.50 m respectively. The horizontal distance between A and B was 150m and the reduced level of B was 121.50m. Calculate the RL of the top of the tower and the horizontal distance from A to the tower.

Please help with b, i & ii The slope distance between two stations A and B measured with EDM when corrected for meteorological conditions and instrument constants, is 113.893 m. The heights of the instrument and reflector are 1.739 m and 1.839 m, respectively, above the ground. To measure the vertical angle a theodolite was set up at A, 1.665 m above the ground and a target at B having height above the ground as 1.632 m. The measured angle above the horizontal was + 4°22′18″. Determine a. The horizontal length of the line AB. b. To what precision the slope angle be measured: i. if the relative precision of the reduced horizontal distance is to be 1/100000. ii. if the reduced horizontal distance is to have a standard error of ± 1.8 mm.
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?
