Triangle ABC has measures a = 2, b = 2, and m∠A = 30°. What is the measure of angle B?

15°

30°

45°

60°

We know that to angle A coresponding side a and to angle B corespond side b so there given that to angle A with measure of 30 degree corespond the side length of side a = 2 but from this given details that side b has length equal 2 so from this reasult that the measure of angle B is equal 30 degrees too same with angle A
