Solution:
a. Mark the angle in a clockwise direction by indicating the turn between the north line and the line joining the centre of the compass to the point P.
The bearing of point P is 048°.
b. Mark the angle in a clockwise direction by indicating the turn between the north line and the line joining the centre of the compass to the point P.
The cardinal point S corresponds to 180°. It is clear from the diagram that the required angle is 60° larger than 180°. So, the angle measured in a clockwise direction from the north line to the line joining the centre of the compass to point P is 180° + 60° = 240°.
So, the bearing of point P is 240°.
c. Mark the angle in a clockwise direction by indicating the turn between the north line and the line joining the centre of the compass to the point P.
The cardinal point S corresponds to 180°. It is clear from the diagram that the required angle is 40° less than 180°. So, the angle measured in a clockwise direction from the north line to the line joining the centre of the compass to point P is 180° – 40° = 140°.
So, the bearing of point P is 140°.
d. Mark the angle in a clockwise direction by indicating the turn between the north line and the line joining the centre of the compass to the point P.
The cardinal point W corresponds to 270°. It is clear from the diagram that the required angle is 20° larger than 270°. So, the angle measured in a clockwise direction from the north line to the line joining the centre of the compass to point P is 270° + 20° = 290°.
So, the bearing of point P is 290°.
