1.	L1 and L2 are two lines whose vector equations are L1:→r=λ(cosθ+√3)^i+(√2sinθ)^j+(cosθ−√3)^k L2:→r=μ(a^i+b^j+c^k), where λ and μ are scalars and α is the acute angle between L1 and L2.If the angle α is independent of θ, then the value of α is
Answer» $L_{1}$ and $L_{2}$ are two lines whose vector equations are $L_{1} : \to r = λ (cos θ + \sqrt{3})^i + (\sqrt{2} sin θ)^j + (cos θ - \sqrt{3})^k$ $L_{2} : \to r = μ (a^i + b^j + c^k),$ where $λ$ and $μ$ are scalars and $α$ is the acute angle between $L_{1}$ and $L_{2} .$ If the angle $α$ is independent of $θ,$ then the value of $α$ is
