The vector w ai bj is perpendicular to the line ax by c and parallel to the line bx ay c It is also true that the acute angle between intersecting lines that do not cross at right angles is the same as the angle determined by vectors that are either normal to the lines or para to the lines Use this information to find the acute angle between the lines below 2x 5y 2 7x 3y 9 The angle is radians Type an exact answer using x as needed SCIE
