Convert Quadrantal Bearings to Whole Circle Bearing
Convert the following quadrantal bearing into whole circle bearing:
1. N 30°30՛ E
2. S 50° E
3. S 20°45՛ W
4. N 25° W
Solution:
How to draw the line for a Q.B ??
For Example: N 30°30՛ E, S 20°45՛ W & for N 25° W.
In case of N 30°30՛ E, the line will be drawn starting from the North line up to 30°30՛ towards the East line.
In case of S 20°45՛ W, the line will be drawn starting from the South line up to 20°45՛ towards the West line.
In case of N 25° W, the line will be drawn starting from the North line up to 25° towards the west line.
Now, the whole circle bearing can be written directly as below:
1. Line OB, W.C.B = 30°30՛
2. Line OC, W.C.B =180° – 50° = 130°
3. Line OD, W.C.B = 180° + 20°45՛ = 200°45՛
4. Line OE, W.C.B = 360° – 25° = 335°
