I thought I calculated the vector components correctly and added them, but apparently something is wrong. A car travels 2.2 km in the x-direction, then turns left 67.5 degrees to the original direction and travels an additional distance of 3.09km. Calculate the x component of the car's displacement. This is what I did: The first vector went 2.2km to the right, so the x component of that vector is 2.2, while the y is 0. Unless I misread the info, the second vector is going 3.09km in the northwest direction. I found the x component of that by multiplying the cosine of 67.5 by -3.09 (negative because it is going in the negative x-axis direction, or so that's how my book explains it). I got -1.182. The y component is unncecessary but I got 2.855 for that. I added the two x components up and I got 1.018 and it's incorrect. I don't know where I went wrong.
