a.) (Triangulation): Two stations B and C were observed from a theodolite set up at station A and following data are recorded as follows: Line AB: azimuth = 345o10’ and distance = 156.45m Line AC: azimuth = 34o25’ and distance = 205.10m Determine the length of BC and its direction in azimuth   b.) (Trilateration): In a trilateration network one of the triangles has the following data: AB = 156.67 m          BC = 202.45m           CA = 185.78m

Question

a.) (Triangulation): Two stations B and C were observed from a theodolite set up at station A and following data are recorded as follows:

Line AB: azimuth = 345o10’ and distance = 156.45m

Line AC: azimuth = 34o25’ and distance = 205.10m

Determine the length of BC and its direction in azimuth

 

b.) (Trilateration): In a trilateration network one of the triangles has the following data:

AB = 156.67 m          BC = 202.45m           CA = 185.78m

If the true bearing of side AB is N15o30’E, determine the bearing of side BC.
