There is not enough information to determine if the triangles are similar

Yes, because teach triangle has an angle measuring 57^o

no, because 34 + 57 ≠ 57 + 89 which means there are not two congruent angles in triangle A to two angles in triangle B

Yes, because 180 - (34 + 57) = 89 which means two angles in triangle A are congruent to two angles in triangle B
