αA = arctg (X1-XA) ...............................................................(3.2)
(Y1-Y2)
Δ 1 = α1 – αA ................................................................... (3.3)

Keterangan:

αA = Sudut jurusan titik A

Δ 1 = Sudut azimuth pada titik PI 1

Perhitungannya :

1. Sudut ∆ pada titik PI.1

∝A

∝1

56°

∝A = arctg (X.A - Xpi.1)
(Y.A - Ypi.1)

= arctg (…………..- ……………..)
(……………. - ……………)

= ……° + ……….° = ……………°

∝1 = arctg (Xpi.1 - Xpi.2)
(Ypi.1 - Ypi.2)
