A car is driven east for a distance of 43 km, then north for 20 km, and then in a direction 27 east of north for 25 km. Determine (a) the magnitude (in km) of the car's total displacement from its starting point and (b) the angle (from east) of the car's total displacement measured from its starting direction.

My answer for displacement is 72KM North-east. And 26 degree. so please help if possible, because this is my last try, and it been telling me i was wrong so far. Thanks
