A plane \pi_1 contains the vectors \overline{i}+\overline{j} and \overline{i}+2 \overline{j}. Another plane \pi_2 contains the vectors 2 \overline{i}-\overline{j} and 3 \overline{i}+2 \overline{k} \cdot \overline{a} is a vector parallel to the line of intersection of \pi_1

Correct Answer is : Cos−1(43√5)

{\Cos}^{-1} ( {4}/{3 \sqrt{5}})
