A
6° 23' 55" convert to decimal degrees
[ 6 + 23/60 + 55/3600] ≈ 6.399°
So
sin (6.399) = opp / 17.03 multiply both sides by 17.03
17.03 sin (6.399) = opp ≈ 1.9 m
B
7° 37' = [ 7 + 37/60] ≈ 7.62°
13.23 sin (7.62) = opp ≈ 1.76m
C
5° 38' 40" = [ 5 + 38/60 + 40/3600 ] ≈ 5.64°
20.35 sin (5.64 ) = opp ≈ 2 m
