If the two vectors are of equal magnitude their resultant will have a direction of 101.5 degrees and a magnitude of 1.79 times either's magnitude.
(101.5 degrees is directly between the two directions you supplied. 1.79 is a result of doubling the cosine of 26.5 degrees - which is the angle between the original vectors and their resultant.)
