If the bearing of P from Q is 300°, will the bearing of Q from P be 600

no.

subtract 180° to face the opposite direction.

No, the bearing of Q from P will not be 600°.

The bearing of an object refers to the angle measured in degrees clockwise from the north direction to the direction of the object. In this case, if the bearing of P from Q is 300°, it means that the angle measured counterclockwise from the direction of Q to the direction of P is 300°.

To determine the bearing of Q from P, we can use the fact that the bearing between two points in opposite directions is the complementary angle. In other words, the bearing from P to Q is 180° plus the bearing from Q to P.

Therefore, if the bearing of P from Q is 300°, the bearing of Q from P would be 180° + 300° = 480°, not 600°.
