[1] A car is driven 215 km west and then 85 km southwest. What is the displacement of the car from the point of origin (magnitude and direction)? Draw a diagram.

[2] I have no idea what equations are necessary for this problem. I reread the chapter, but this problem in particular is stumping me.

[3] Originally, I thought I could make a triangle by using the vector of the 215 km west, the 85 km southwest, and the distance between the origin and the head of the 85 km southwest vector as sides. I thought if I could split the big triangle into two right triangles, I could use trigonometric functions to find the displacement, to no avail...
