In tacheometry survey, an intercept of 0.755m was recorded on a staff which was believed to vertical, and the vertical angle measured on the theodolite was +15º. Actually, the staff which was 4 metres long was 0.14m out of plumb bob and leaning backwards away from the instrument position. Assuming it was an anallatic instrument with a multiplying constant of 100, what would have been the error in the computed horizontal distance?
