an airplane flying at 550 miles per hour has a bearing of N 52(DEGREES)E. After flying 1.5 hours, how far north and how far east has the plane traveled from its point of departure?

This is what I got.
Plane travelled 825m in 1.5 hrs.
sin(52) = a/825 = 650m N
cos(52) = b/825 = 508m E 
an airplane flying at 550 miles per hour has a bearing of N 58(DEGREES)E. After flying 1.5 hours, how far north and how far east has the plane traveled from its point of departure?
