It is in 4 quadrant, to convert it from RB to WCB = 360-Bearing of line.

360-87 = 273.

How can we know that the bearing is in which quadrant?

I think north west is in 3rd quadrant. How you say that is in 4th quadrant?

The whole circle bearing (W.C.B) of a line is the horizontal angle measured clockwise from the North limb of the meridian.

Here, clearly given its N87°W, and North to West is 4th quadrant so the ans. is 360-87= 273.

Because in WCB method all bearing are measured north direction and in this case, it is in anticlock wise so 360 - 87 = 273.

How to know that it's anticlock wise?

It is in 4th quadrant, because it is northwest. North west is at 4th quadrant and it is the clockwise direction it will be 360-87=273.

360°-87°= 273°.
