Calculate the Horizontal Distance
A surveyor's total station measured slope distance near station 3245+26.35 is recorded as 437.380-m with a zenith angle of 118º 48' 07" and a south easterly bearing. The horizontal distance (m) is most nearly:
Solution: Sketch the statement:
α = 118º 48' 07" - 90º 00' 00"
α = 28.80
Cos 28.80 = x/437.38
X = (437.38)(0.8763)
X = 383.276-m
Distance ABC was measured with a 30m. Chain tested and found to be correct in the beginning of the work .after measuring AB=1.2 km chain was found to be 10 cm. To long chaining was
