If so
The Sine Rule is fairly easy to remember
The Cosine Rule is given on the formula sheet
The rearrangement of the Cosine Rule is a GCSE level skill
It really depends on what information you have - if you put the information into a rule and you have everything apart from the value you are meant to be finding then you are using the correct rule
