Question

Given the bearing N30°W, determine the corresponding Whole Circle Bearing (WCB). \

 Given: - Bearing = N30°W - Find WCB

• A. 330°
• B. 150°
• C. 90°
• D. 180°

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.

Answer 1

The Correct Option is A

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 \( \mathbf{330°} \).
