(b) The coordinates of point A are E 311.617 m, N 447.245m, The distance from A to B = 57.916m and bearing from A to B = 37°11'20", distance A to C = 85.071 m and bearing A to C= 205°33'55". (i) Calculate the coordinates AB and C. (i) Illustrate the positions of the point AB and C (ii) Find the distance and full circle bearing for BC.

A is a point having an elevation of 130.48 m above datum, and B and C are points of unknown elevation. B is in between A and C. By means of an instrument set 1.22 m above B vertical angles are observed that to A being -14°45' and that to C being +8.32. The horizontal distance AB is 547.20 and the horizontal distance BC is 923.25 m. Making due allowance for earth's curvature and atmospheric refraction. Compute the elevation (meters) of C.

Given: θ=20o30' Upper Reading=2.800 m Middle Reading=2.000 m (rod reading (RR)= h)  Lower Reading=1.200 m Height of Instrument=1.20 m Elevation at point O=140.50 m K=100 C=0   Compute the horizontal distance Determine the vertical distance Calculate the inclined distance find the elevation of point P

What are the coordinates of station P?
