A stadia measurement was undertaken with a theodolite having an internal focusing telescope and stadia interval factor of 98.8. When a backsight was taken on a turning point whose elevation is 205.62 m, the rod interval observed was 1.94 m; and with the horizontal hairs set at 1.50m on the rod, the vertical angle reading was -13°45'. For a foresight to a control point, the rod intercept was 1.17 m, and with the horizontal hairreading of 1.60 m on the rod, the vertical angle observed was +7°18'. Determine the elevation of the line of sight at the instrument point and the elevation of the point on which the foresight was taken (Control Point)
