Question:
Check whether the lines given by equations x = 2lambda + 2 y = 7lambda + 1 , z = - 3lambda - 3 and x = - mu - 2 , y = 2mu + 8 , z = 4mu + 5 are perpendicular to each other or not
Answer:
We know that,
and
Then, two lines L1 and L2 are perpendicular if
In the question,
Given that,
and
and
Hence, Lines are perpendicular to each other
