There are two forces vectors, one of 5 N and other of 12 N. At what angle the two vectors be added to get resultant vector of 17 N, 7 N and 13 N respectively?

For 17 N both the vector should be parallel i.e., angle between them should be zero0 For 7 N both the vectors should be antiparallel i.e., angle between them should be 1800.For 13 N both the vectors should be perpendicular to each other i.e., angle between them should be 900.
