1. The problem statement, all variables and given/known data A car is driven east for a distance of 55 km, then north for 34 km, and then in a direction 30° east of north for 23 km. Draw the vector diagram and determine the total displacement of the car from its starting point. 2. Relevant equations the answer = arc tan (ay/ax) 3. The attempt at a solution The magnitude is 87 km. But I don't understand how to find the direction (in degrees) counterclockwise from east. You have to use that tangent formula. But I don't know what numbers to plug in for the x and y component.
