There are 3 boats, P, Q and R. Boat Q is 7km from boat P on a bearing of 327. boat R is 15km from boat P on a bearing of 041. Find the distance between boats Q and R to 1dp?
I'm not sure where to begin with this and I'm struggling to understand the bearings

Explanation:
From the diagram we can see that we need to find the line QR
First we calculate angle at P, this is:
Using the Cosine Rule:
When solving problems like this, it is best to start with the point that the bearings are given from and mark the vertical line representing NORTH.
This is where all the measurement are taken from. Angles are measured clockwise from the vertical. The angle
As a note:
Bearings are given as 3 figures, that is why we have angles like 041. This is just
Hope this helps.
