The constant K and C for 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 upper reading was recorded to be 1.915m if the vertical angle of the instrument was 6°43' and height of instrument above A was 1.82m.Determine the horizontal distance between A and B.
