Condition: Find the angle between the line \( (A B) \) and the plane \( (C D E) \), where \( A(1 ; 2 ; 2), B(-1 ; 26 ; 1), C(2 ; 0 ; 4) \), \( D(2 ; 26 ; 1), \quad E(26 ; 2 ; 3) \). First write the equations of a line and a plane.
Solving problems in three-dimensional space using tangents and normals, both straight lines and planes.
