Hi, can you please solve this again? The one I saw have some errors. Thank you so much!
The constant K and C for certain instrument were 99.81 and 0 respectively. The ground makes a uniform slope of 9.8% 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 reading was recorded to be 1.99m if the vertical angle of the instrument was 6.49° and Height of instrument above A was 1.7m. Determine the horizontal distance between A and B.
