John - The actual velocity is the combination of the plane velocity and the wind velocity, so to arrive at the wind velocity you must subtract the plane velocity from actual.

You can break the problem down into x and y components:

y = 840 sin(180+49) - 870 sin(180+44)

x = 840 cos(180+49) - 870 sin(180+44)

wind velocity = (x^2 + y^2)^(1/2)

wind direction = arctan(y / x)

John - I know some provide complete answers but Wyzant discourages that and I agree with them. It is important to work through and understand each step of a problem. That way you can work similar problems. Try to solve using the info I have given. Perhaps other students have worked it the way I have. If you would like more help I would be glad to set up one or more tutoring sessions with you.
