You have two solutions
sinA/a = sinb/b
sin 60 = square root of 3 divided by 2 This number is around .7
.7/9 = sinB/6 Therefore sinB = .7*6/9 = 4.2/9 This number is slightly less than .5 If the sinB is around .5 we can have two angles that have sins that are .5. These two angles are around 30 degrees and 150 degrees. Therefore, there are two solutions to this problem.
