If $ \hat{i} + \hat{j}, \hat{j} + \hat{k}, \hat{i} + \hat{k}$ are the position vectors of the vertices of a triangle $ABC$ taken in order, then $\angle A$ is equal to

Let $\vec{a}, \vec{b}$ & $\vec{c}$ be non-coplanar unit vectors equally inclined to one another at an acute angle $\theta$. Then $| [ \vec{a} \; \vec{b} \; \vec{c}] |$ in terms of $\theta$ is equal to

If $m_1, m_2, m_3$ and $m_4$ are respectively the magnitudes of the vectors $a_1 = 2i - j + k, a_2 = 3i - 4j - 4 k $ $a_3 = i + j - k$ and $a_4 = - i + 3j + k , $ then the correct order of $m_1, m_2, m_3 $ and $m_4$ is
