The **direction **to a point is stated as the number of degrees east or
west of north or south.
For example, the direction of *A* from *O* is N30ºE.
B is N60ºW from *O*.
C is S70ºE from *O*.
D is S80ºW from *O*.
###### Note:
N30ºE means the direction is 30º east of north.
The **bearing** to a point is the angle measured in a clockwise
direction from the north line.
For example, the bearing of *P *from *O* is 065º.
The bearing of *Q *from *O* is 300º.
Note:
The direction of *P* from *O* is N65ºE.
The direction of *Q *from *O* is N60ºW.
A **bearing** is used to represent the direction of one point relative
to another point.
For example, the bearing of *A *from *B* is 065º.
The bearing of *B *from *A* is 245º.
###### Note:
- Three figures are used to give bearings.
- All bearings are measured in a horizontal plane.
Example 19
A boat sails from a certain port in the direction N30ºW. After the
boat has sailed 20 km, how far is it west of the port?
##### Solution:
Let the boat be *x* km west of the port.
So, the boat is 10 km west of the port.
Example 20
A cyclist travels 10 km south, then 8 km east. Find the cyclist's
bearing from her starting point to the nearest degree.
##### Solution:
So, the cyclist's bearing is 141º from her starting point.
