The following data were obtained by stadia observations: Vertical angle = + 9°25’, upper and lower stadia hair readings are 2.352 and 0.995 m., respectively. The stadia interval factor is known to be 99.00 and C is 0.381 m. The height of the instrument above the instrument station (point A) is 1.496 and rod reading is taken at 1.589m. Determine the following:
a. Draw the diagram
b. the horizontal stadia distance
c. the vertical stadia distance
d. the elevation on the point where the rod was held
