P. 61
α = 338°08’32”
Jadi ∆x = 8 x sin 338°08’32” = - 2,978 m.
G) Perhitungan di titik P7
P 7 J = 23,599 m
α = 125°43’43”
Jadi ∆x = 23,599 x sin 125°43’43” = 19,157 m.
BP 7.1 J = 7 m
α = 116°03’06”
Jadi ∆x = 7 x sin 116°03’06” = 6,288 m.
D 7.2 J = 18,999 m
α = 83°58’18”
Jadi ∆x = 18,999 x sin 83°58’18” = 18,894 m.
D 7.3 J = 1,6 m
α = 106°00’56”
Jadi ∆x = 1,6 x sin 106°00’56” = 0,430 m.
H) Perhitungan di titik P8
P 8 J = 18,999 m
α = 106°00’56”
Jadi ∆x = 18,999 x sin 106°00’56” = 18,262 m.
D 8.1 J = 5,2 m
α = 29°27’34”
Jadi ∆x = 5,2 x sin 29°27’34” = 2,557 m.
D 8.2 J = 7,197 m
α = 77°32’01”
