Inner Circle Reading of the Double Vernier of a Transit 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? A. 175° 42' C. 184° 18' B. 193° 8' D. 181° 3' Solution Click here to expand or collapse this section Inner Circle Reading = 180° + 4° + 18’ = 184° 18’ ← Answer: [ C ] Outer Circle Reading = 170° + 5° + 30' + 12' = 175° 42' Checking: Inner Circle Reading + Outer Circle Reading = 360° 184° 18' + 175° 42' = 360° (okay!)
