**bonjo**, Thursday, June 6, 2013 at 4:26amif the * is the degrees, then you need to draw the vectors according to their direction. you can use a graph paper and make your own scale: say one unit cube is 10km/hr. then use the protractor to draw the vectors taking an horizontal line as zero degrees. then draw the vectors. you may also need to use pythagoras theorem to get the actual magnitude of each vectors. Then subtract the vectors by inverting the direction of the wind vector (recall vector subtraction). the resultant of the two vectors is the velocity of the plane.
