The angle θ between two lines whose direction ratios are proportional to a1, b1, c1 and a2, b2, c2 respectively is given by:
CALCULATION:
Here, we have to find the angle between the two lines having direction ratios (6, 3, 6) and (3, 3, 0).
Here, a1 = 6, b1 = 3, c1 = 6, a2 = 3, b2 = 3 and c2 = 0
As we know that, if θ is the angle between two lines having direction ratios proportional to a1, b1, c1 and a2, b2, c2 is given by:
⇒
⇒
⇒ θ = π/4
Hence, correct option is 2.
