1. Vector A has x and y components of −20 cm and 19 cm, respectively; vector B has x and y components of 11.1 cm and −20 cm, respectively. If A−B +3 C = 0, what are the x and y components of vector C ?
2. Not too sure. I am thinking that using trigonometry or Pythagorean theorem.
3. I attempted to find vector A and B by using Pythagorean theorem, which I roughly get to be 27.6 and 22.9. I am unsure how the negative values of the x and y components affect the actual number for the vectors. I know that I could also find the angles of the vectors using trig, but as stated earlier I am unsure how negative x and y components affect the magnitude of the vector except for it going in a different direction. After I know all that information I still do not know how to solve for the components of vector C. I am still relatively new with vectors so it would be great if you could explain things in the simplest terms possible.Thanks
