Problem Figure P-SF01 is a double vernier of a transit and the dashed line indicate the two sets of coincident lines. What is the reading of the inner circle?
Solution
Outer Circle Reading = 170° + 5° + 30' + 12' = 175° 42'
Checking: Inner Circle Reading + Outer Circle Reading = 360° 184° 18' + 175° 42' = 360° (okay!)
