Line 1 = -4i + j +3k + s(i + 5j - 2k)
Line 2 = 3i - 7j + 9k + t(2i - 3j + k)
The lines are skew.
Question: Find the position vector of the point C on line 2 such that ∠ABC = 90°.
Annnd...i have no idea how...I've tried random things but nothing works.
The answer is -7i + 8j + 4k
Any help or prods in the right direction would be appreciated.
Thank-you very much!
