3.3.25 Line and plane in space
condition: Find the angle between the line \( A B \) and the plane \( C D E \), where \( A(1 ; 2 ; 2), B(-1 ; 2 ; 1), C(2 ; 0 ; 4) \), \( D(2 ; 2 ; 1), \quad E(2 ; 2 ; 3) \). First write the equations of a line and a plane.
Straight lines and planes in space. Intersection of lines and planes, calculation of the distance of a line and a plane, angles between lines and planes, finding equations of lines and planes in space, and much more.
