# Bearing and Distances

Welcome to class!

In today’s class, we will be talking about bearing and distances. Enjoy the class!

### Bearing and Distances

Angle of Elevation

This is the angle formed between the normal eye level and the line through which the observer views an object above.

#### BEARING AND DISTANCES

Bearings can be defined as the angular relationships between two or more places. Bearings are specified in two ways:

Cardinal Points: It is specified in reference to the north and south. E.g. N450E, S600W

###### General Evaluation
1. Find  the  corresponding bearing  of the  following: (a)N640W  (b)0640  (c)S420E  (d) 2340
2. If the bearing of  X  from  Y  is  N640W. Find the bearing of  Y   from  X.
3. A boat sails 6km from a port X on a bearing of 0650 and thereafter 13km on a bearing of 1360. What is the distance and bearing of the boat from X?
4. Find the angle of elevation to the nearest degree of the top of a church tower 180m high from a point on the ground 75m from its foot.

In our next class, we will be talking about Statistics.  We hope you enjoyed the class.
