vector components 
Summary
Any vector can be split into a horizontal part at a vertical part. These are called components using sine and cosine you can calculate how much of the vector act in each direction this makes adding vectors much easier, especially when dealing with angles
Components = horizontal + vertical parts
Original vector = hypotenuse
use trig:
Sin = opposite/hypotenuse
Cod = adjacent/hypotenuse
steps
Break each vector into X and Y parts
Add all X components
Add all Y components
Use Pythagorean theorem
Use trig to find direction
