Let's choose the "east" direction as positive x-direction. The new velocity of the jet is the vector sum of two velocities: the initial velocity of the jet, which is
along the x-direction
in a direction 
north of east.
To find the resultant, we must resolve both vectors on the x- and y- axis:
So, the components of the resultant velocity in the two directions are
So the new speed of the aircraft is:
