A plane is flying E40N @ a speed of 600km/h. The wind blowing @ 10km/h in the direction N20W. Determine the resultant velocity of the plane. So I get W + V Vectors = 600^2 + 10^2  2(600)(10)cos110= ?364204.2417 = 603.49 The angle I am trying to . I use the sine law ; sinAlpha/10= sin110/603.49 = alpha = sin^1(10sin110)/603.49. = I get an angle of .89 degrees.. I have been trying to figure if I am using the angle of 110 improperly but it seems to check out. Any advice?
