Question

Based on the diagram, which expresses all possible lengths of segment AB?

Answer 1

where's the diagram of the quedtion

Answer 2

The answer is as follows sinA/a  = sinB/b

= sinC /c so sin A /54  = sin B/27 = sin C/ c, and c = AB and besides, sinC > sinB > sinA  , so the only answer possible correct answer for the above question is 27 < AB < 81
