Extracted text: PROBLEM 1: A survey party proceeded to do their stadia survey work as follows: the transit was set up at a point A and with the line of sight horizontal, took rod readings with the rod at point B and C, which were then measured to have taped distances from A to 200 m., and 60 m. respectively. Rod B Rod C Stadia Interval 2.001 m 0.600 m The distance from the center of the instrument to the principal focus was recorded as 0.30 m. Then they went on to survey other points, with some of the data recorded as follows: with the transit at point D, two points E and F were sighted. Rod E Rod F Stadia Interval 2.120 m 3.560 m Vertical Angle + 4°22' - 3°17'
