Let u , v and x be VECTORS.
A is angle between u and v.
u . x = |u| |x| cos A
v . x = |v| |x| cos A
(u . x) / (v . x) = |u| / | v|
|u . x| / |v . x| = |u| / |v|
Answer is YES

The fee of sqrt(500) is right, yet all vectors have the two a value and direction. The direction of the consequent vector is down and to the wonderful or 3 hundred ranges.

Because x is the angle bisector, cos(u^x) = cos(v^x) which means that
ux/u = vx/v
or
ux/vx = u/v
