sin in a non-right angle triangle

[needhelpforGCSE's]

if a over sinA is equal b over sinB and you do not know b, why does it not work to do sinB*(a/sinA) to get b.

Can you please provide an example where it did not work out?

3.4/sin30 = 6.8 so sin78*6.8=6.65140368 should be right but i was told it was wrong
