संकल्पना:

एक त्रुटि मुक्त आयोजित अनुप्रस्थ के लिए:

ΣL = 0, ΣD = 0

ΣL = सभी बाजूओं के अक्षांश का बीजगणितीय योग

ΣD = सभी बाजूओं के विचलन का बीजगणितीय योग

खण्ड AB के लिए

अक्षांश = L cos θ & Departure = L sin θ

गणना:

From the figure 

∴ θ =  - 30°

The whole circle bearing of the line AB is

α = - 30° + 360° = 330°
