Vectors $\vec{A}$ and $\vec{B}$ are in the $xy$-plane. Vector $\vec{A}$ is in the $+x$-direction, and the direction of vector $\vec{B}$ is at an angle $?$ from the $+x$-axis measured toward the $+y$-axis. If $?$ is in the range $0^{?}???180^{?}$, for what value of $?$ does the vector product $\vec{A}\times \vec{B}$ have its maximum value? Express your answer in degrees.
