3. The upper and lower stadia hair readings on a stadia rod held at station B were observed as \( 4.50 \mathrm{~m} \) and \( 1.35 \mathrm{~m} \), respectively, with the use of a transit with an internal focusing telescope and having a stadia interval factor of 99.75. The height of instrument above station \( \mathrm{A} \) is \( 1.52 \mathrm{~m} \) and the rod reading is taken at \( 2.50 \mathrm{~m} \). If the vertical angle observed is \( -25^{\prime} 15^{\prime} \), determine the following; a. Horizontal, vertical, and inclined distances from the instrument to the station sighted. b. Difference in elevation between stations A \& B. c. Elevation of station \( B \), if the elevation of station A is \( 150 \mathrm{~m} \) amsl.
