In the triangle ABC opposite the angle A = 55 ° lies the side BC, opposite the angle C = 120 ° lies the side AB. In a triangle, opposite the larger angle lies the larger side, opposite the smaller angle lies the smaller side.
Since angle A is less than angle C, then the side BC, which lies opposite the angle A, will be less than the side AB, which lies opposite the angle C.
Answer. AB> BC.
