Option 1 : S 68 degree E

Explanation

Given,

WCB = 112 ° (i.e II nd quadrant)

 So the line lies in the SE quadrant.

 Angle from south = 180 - 112 = 68 ° 

∴ Quadrantal Bearing = S 68° E

Note:

Difference between quadrantal bearing and Whole circle bearing –

Quadrantal Bearing

Whole Circle bearing
  • In this system, the bearing of line is measured eastward or westward from north or south whichever is near.
  • The directions can either be clockwise or anti clockwise depending upon the position of the line
