Does that mean that whenever we have to use the sine rule, we should check whether it could be an ambiguous case or not? Also thank you very much for the great video :)
They're both technically solutions, but if you are asked this on an exam, for example, they'll ask you specifics about it so you know what you're looking for. The hint is usually something like 'angle XYZ is obtuse, ...'

hi! is there any way to know at a glance if a case is ambiguous or not?
