Deciding what Angle to use....HELP PLEASE !!

The question is this: A hiker sets out on a trek heading (N35degreesE) at a place of 5.0 km/h for 48.0 mins. He then heads west at 4.5 km/h for 40.0 min. Finally, he heads (N30degreesW) for 6.0 km, until he reaches a campground 1.5 hours later. A) Find his total displacement using vector components. SO, i used Ax = 4.0 cos 35degrees = 3.27 Ay = 4.0 sin 35degrees = 2.29 Then I looked at the answers and it said I should have used the angle 55 degree angle instead of
