A car is driven east for a distance of 43 km, then north for 25 km, and then in a direction 26° east of north for 26 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.

Use the method of any of the "related problems" below. All they did was change the numbers a bit.
