Compute all parts of following problem:
Problem: A canoe has a velocity of 0.55m/s southeast relative to the earth. The canoe is on a river that is flowing 0.60m/s east relative to the earth,
Part A: Find the magnitude of the velocity of the canoe relative to the river.
Part B: Find the direction of the velocity of the canoe relative to the river.
I need help to solve the above problem and express your answer as an angle measured south of west.
