(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the line that passes through point M(-5,2,-1) and cuts the line:

(x-1)/3 = y/5 = (z+2)/-2 at right angle (two lines are perpendicular)

2. Relevant equations

r = a + [tex]\lambda[/tex]b

3. The attempt at a solution

i used the scalar product a*b = |a| *|b| * cos(a,b) , but i don't seem to have enough knowns to solve the problem, or should i try something else

Also, if someone would like to give me a hint on understanding and approaching these problems

(i.e. lines and planes meeting each other... ) in most universal sense. I try to picture things but problem appears when something has to be written down. Can't see analogy of any kind.

Help please
