Question 883248: Points A and B are 100m apart on a coastline.
B is directly east of A.
A lighthouse is out at sea.
The bearing of the lighthouse is
163 degrees from A and
219 degrees from B
The angle of elevation of the top of the lighthouse from A is 25 degrees.
Find the distance of the lighthouse from A.
Find the height of the lighthouse.
-----------------
I dont understand bearings.
Are the bearings now the length?
I know Im suppose to use my sine rules for this question.
I know if i put a protractor from A to the lighthouse it is 163 degrees
and if i do the same with B to lighthouse i get 219. I just dont understand how to use the information of bearings.
thank you

Bearing is the angle. Nothing to be afraid of.
