Given triangle ABC, which equation could be used to find the measure of ∠B?

right triangle ABC with AB measuring 6, AC measuring 3, and BC measuring 3 square root of 5

cos m∠B = square root of 5 over 5
sin m∠B = square root of 5 over 5
cos m∠B = square root of 5 over 2
sin m∠B = 2 square root of 5 all over 5
