A surveyor aims to determine the horizontal
distances between 4 points P, Q, Y and Z
along the centerline of a road with a known
slope angle of 0=10°
The unknown parameters include x1:
horizontal distance between P and Q, x2:
horizontal distance between Q and Y, x3:
horizontal distance between Y and Z.
The surveyor makes three slope distance
measurements between these 4 points
which are given in the table below.
