A jogger travels a route that has two parts. The first is a displacement A of 2.95 km due south, and the second involves a displacement B that points due east. If the resultant displacement A+B has magnitude 4.13 km, what is the magnitude of B?

Im not sure if i just do 4.13-2.95 or if it is more complicated than that??
