130 is heading from north
d=vt=1100 km/hr * 3 hrs =3300km ,, distance along hypotenuse
sketching a triangle with east as one leg, hypotenuse along 130 heading
supplement of 130 is 50 deg, which is also top vertex angle, opposite horizontal line that is east.
in short, sin 50 deg = x/3300, or x=3300*sin50 = 2527.9
