Note that if the three forces were of equal magnitude, then they would cancel.  So, frame the problem this way.  You have

A force of 10N + 2N in the direction AB
A force of 10N in the direction BC
A force of 10N in the direction CA.

The components of magnitude 10N cancel, leaving you with a force of magnitude 2N in the direction AB.
