Extracted text: The upper and lower stadia hair readings on a stadia rod held at station B were observed as 4 and 2.3m, respectively, with the use of a transit with an internal focusing telescope and having a stadia interval factor of 87.9. The height of the instrument above station A is 1.43m and the rod reading is taken at 2.15m. if the vertical angle observed is -23°34', determine the following: A. Horizontal stadia distance ( B. Vertical stadia distance C. Inclined stadia distance
