    Vector Geometry Numerical Question

    I need a fast shotgun method to spit out the coordinates of both vectors, there has to be something out there that I don't know of!

    Thanks in advance guys!

    Let A(x_a, y_a) and B(x_b, y_b). Knowing that A+B+P=0 we can write 2 equations:

    x_a+x_b=0
    y_a+y_b=19

    or

    |A|cos(a)+|B|cos(b)=0
    |A|sin(a)+|B|sin(b)=19

    So, you can find lengths |A| and |B| and coordinates from this system.

    Works well, thanks!
