Angles W6 Quiz

1. 1A surveyor observes directions on both faces to 3 points (X, Y, and Z). Y is the RO at a bearing of about 95°, X is approximately southwest, and Z is about north (you may find it helpful to draw a diagram). Put these horizontal observations in the correct order:
   
   1 = [blank_start]LF to Y[blank_end]
   2 = [blank_start]LF to X[blank_end]
   3 = [blank_start]LF to Z[blank_end]
   4 = [blank_start]plunge telescope and rotate 180°[blank_end]
   5 = [blank_start]RF to Z[blank_end]
   6 = [blank_start]RF to X[blank_end]

4. 4The present magnetic declination is 24° 10' E and has been increasing at a rate of + 05' per year since records began. You are looking at a survey plan that is 120 years old. On that old plan a boundary line shows a magnetic bearing of 96° 00'.
   
   What is the true bearing of this boundary line? Show as DD.MM (eg 34.02)
   Hint: draw a well labelled diagram to solve this problem

   [blank_start][c][blank_end] = the final value for P (show in D.MS, eg 21.3456)
   [blank_start][d][blank_end] = the final value for Q (in D.MS)

   [blank_start][b][blank_end] = mean reading to Q (show just seconds in usual format, eg 02, 15, etc)
   [blank_start][c][blank_end] = mean reading to R (show just seconds in usual format, eg 02, 15, etc)
