An anthropologist is studying the cultural significance of ancient structures that align with celestial bodies. They model the direction vector of a sunrise alignment as \(eginpmatrix 3 \ 4 \endpmatrix\) and need to find a perpendicular direction vector for a shadow alignment. Find \(x\) so that the vectors \(eginpmatrix 3 \ 4 \endpmatrix\) and \(eginpmatrix x \ -6 \endpmatrix\) are orthogonal. - Nelissen Grade advocaten
