Thank you. |

You can do that in general, but it's a lot easier to use the component method. Have you learned that yet?

For problem 1 you are correct. The two vectors are in the same direction so you can simply add the two magnitudes. But remember you still need to put the direction (angle) in for your final answer. The answer would be 7.80 km at 35 degrees N of W.
