Question

what is the difference in elevation b/w point b and c? what is the slope length between the ground surface at point b and the ground surface at c? what is the elevation of point c if point a is at an elevation of +0316.15m above mean sea level?

2 points B & C were observed from point A where the instrument was set up at a
height of 1.25m. Points B & C are ahead of point A. The surveyor used an
internally focusing telescope with a stadia interval factor of 100. The
following data was recorded as observed for points B & C.
