Homework Statement
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.
Homework Equations
the answer = arc tan (ay/ax)
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.
