The constants Kand C fora certain instrument were 100 and 0 respectively. The ground makes a uniform slope of 12% from point A to point B. With the instrument at A and staff at B, readings were taken but due to obstruction in the line of sight, only the upper reading was recorded to be 1.915m. If the vertical angle of the instrument was 6 degrees and 45minutes and height of instrument above A was 1.82 m, determinethe horizontal distance between A and B.*
