Given the bearing N30°W, determine the corresponding Whole Circle Bearing (WCB). \
Given: - Bearing = N30°W - Find WCB
Given the bearing N30°W, determine the corresponding Whole Circle Bearing (WCB). \
Given: - Bearing = N30°W - Find WCB
Given: - Bearing = N30°W - Find WCB
Show Hint
In surveying, to convert a bearing to WCB, start from 360° for North, then subtract the angle for bearings with "West". For bearings with "East", simply add the angle.

- 330°
- 150°
- 90°
- 180°
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Convert the bearing to WCB
The bearing N30°W means 30° west of the north. To convert this to WCB, we use the following process:
Start from North, which is 0°. Moving 30° to the West, we subtract 30° from 360°:
\[ \text{WCB} = 360° - 30° = 330° \] Thus, the WCB is \( \mathbf{330°} \).
The bearing N30°W means 30° west of the north. To convert this to WCB, we use the following process:
Start from North, which is 0°. Moving 30° to the West, we subtract 30° from 360°:
\[ \text{WCB} = 360° - 30° = 330° \] Thus, the WCB is \( \mathbf{330°} \).
