(adsbygoogle = window.adsbygoogle || []).push({}); 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.
