Option 4 : 38o
Concept:
Whole circle bearing of any line is its deviation measured in the clockwise direction from the north end reference.
Important table for conversion of a whole bearing reding to the quadrantal bearing is given below:
|
Sr No. |
Whole Circle Bearing (WCB) |
Quadrantal Bearing (QB) |
Quadrant |
|
1 |
0° to 90° |
WCB |
NE |
|
2 |
90° to 180° |
180° - WCB |
SE |
|
3 |
180° to 270° |
WCB – 180° |
SW |
|
4 |
270° - 360° |
360° - WCB |
NW |
Calculation:
Given bearing exist in the first quadrant (0° to 90°), so WCB equal to QB
WCB = 38°
