1. The problem statement, all variables and given/known data
A boat leaves the dock and sails in a direction of 70. Once reaching its destination on the opposite shore, it sails
in a direction of 272 and docks 150 km north of its original starting position. What is the total distance the boat
has traveled?

2. Relevant equations
Sine Law


3. The attempt at a solution
I don't think I'm getting the right answer because I'm not representing the problem correctly. This is how I'm representing the problem then I just simply use AAS

Your angles are incorrect- they should be measured from north in a clockwise direction. Using this, you should be able to draw the correct diagram, where the final poistion is due north of the starting position.

I assume the 272° is with respect to the 'horizontal axis'?
