a plane flies due north at 225km/h. a wind blows it due east at 55km/h. what is the magnitude and direction of the plane's resultant velocity?

okay, one plane is flying north, straight up and the wind blows the plane east [right]. This is almost similar to pythagorean theorem. My guess is to use x^2 + y^2 = z^2. But im pretty sure there's a formula for this in the first or two chapters of the physics book. Look there at use that formula. But in this case you have to find x which is opposite to the wind and plane.
it is pretty simple. to find the magnitude use the pythagorean theorem to find the resultant and then to the tangent inverse to find your angle
231.6km/h
