Answer
North 240.41 miles
East 143.10 miles
Work Step by Step
Total displacement in North direction will be cos component(about bearing angle) of the two displacements
$ = 170 \cos 18° + 120 \cos 49° = 161.68 + 78.73 = 240.41\ miles$
Total displacement in North direction will be $\sin$ component(about bearing angle) of the two displacements
$ = 170 \sin 18° + 120 \sin 49° = 52.53 + 90.57 = 143.10\ miles$
