Question
Find the equal height of towers at triangulation stations A and C so that line AC will clear the
elevated ground between A and C by 6m. with the instrument set at point B, the observed
vertical angle to ground station A is 0 0 55’ and the vertical angle to ground station C is 0 0 48’.
Elevation of A is 237m. Distance AB is 10km and distance of BC is 8.7km. Yhe instrument set-up
at B is 2.7m above the ground. Use hcr= 0.067k ^2
