SUMMARY
The problem involves calculating the magnitude of vector X when added to vector Y, defined as 12i - 16j. The resultant vector is aligned with the positive x-axis and has the same magnitude as vector X. The correct magnitude of vector X is determined to be 20.7, as it satisfies the condition of the resultant vector's direction and magnitude.
