α = 116°03’06”
Jadi ∆Y = 7 x cos 116°03’06” = - 3,074 m.
D 7.2 J = 18,999 m
α = 83°58’18”
Jadi ∆Y = 18,999 x cos 83°58’18” = 1,995 m.
D 7.3 J = 1,6 m
α = 106°00’56”
Jadi ∆Y = 1,6 x cos 106°00’56” = 1,541 m
H) Perhitungan di titik P8
P 8 J = 18,999 m
α = 106°00’56”
Jadi ∆Y = 18,999 x cos 106°00’56” = - 5,242 m.
D 8.1 J = 5,2 m
α = 29°27’34”
Jadi ∆Y = 5,2 x cos 29°27’34” = 4,528 m.
D 8.2 J = 7,197 m
α = 77°32’01”
Jadi ∆Y = 7,197 x cos 77°32’01” = 1,554 m.
I) Perhitungan di titik P9
P 9 J = 6,995 m
α = 62°07’52”
