Answer» A line segment $A B$ of length $2$ units, where $A = (1, 0)$ is rotated in anticlockwise direction through an angle $15^{\circ}$ about $A$ . If initially $A B$ is making an angle $45^{\circ}$ with the positive direction of $X$ - axis in anticlockwise direction and the distance between origin and the new position of $B$ is $k$ units, then the value of $k^{2}$ is
