Hi, Im having problems with this question:

A boat heads north and 20kph

A wind is blowing SE with a constant speed of 2ms^1

a) Find the magnitude of the speed of the boat

b) Find the bearing it travels at

**************

Im having problems with the triangle, drawing it out makes the 2 ms^1 the hypotenuse when, to find the speed shouldnt be the hypotenuse i.e the hypotenuse has to be found?

The using pythagoras I get the resultant being 5.2ms^1 which is complete rubbish.

Please could anyone give me some helpful pointers please?

Thankyou very much in advance!
