Calculate the angle between a 20 N force and a 30 N force so that their resultant is 40 N

Calculate the angle between a 20 N force and a 30 N force so that their resultant is 40 N

Calculate the angle between a 2N force and a 3N force so that their resultant is 4N.

The square of the resultant of two forces 4N and 3 N exceeds the square of the resultant of the two forces by 12 when they are mutually perpendicular. The angle between the vectors is
