P. 67
α = 170°00’54”
Jadi ∆Y = 2 x cos 170°00’54” = - 1,969 m.
D 1.2 J = 6,8 m
α = 273°13’21”
Jadi ∆Y = 6,8 x cos 273°13’21” = 0,382 m.
D 1.3 J = 8 m
α = 359°37’17”
Jadi ∆Y = 8 x cos 359°37’17” = 7,999 m.
D 1.4 J = 10,798 m
α = 58°49’09”
Jadi ∆Y = 10,798 x cos 58°49’09” = 5,591 m.
D 1.5 J = 23,997 m
α = 86°18’59”
Jadi ∆Y = 23,997 x cos 86°18’59” = 1,542 m.
D 1.6 J = 28,997 m
α = 108°49’38”
Jadi ∆Y = 28,997 x cos 108°49’38” = - 9,358 m.
B) Perhitungan di titik P2
P 2 J = 30 m
α = 291°34’49”
Jadi ∆Y = 30 x cos 291°34’49” = 11,034 m.
