The compass in a plane indicates that the plane is heading due east, with an airspeed of 250 km/h (Vpa). A steady wind is blowing with a magnitude of 75km/h, which increases the velocity of the plane, relative to the ground. If the plane is going along a direction East 12 degrees North, what is the magnitude of the plane’s velocity relative to the ground?
Answer: 299 km/h
I feel like I can't answer this question unless I know the angle in which the wind is blowing. Can someone tell me how to approach this problem please
