why does the mark scheme not take away 38* aswell from 180?
The angle A can have two solutions either 61.4° or 118.58°
It says to find the size of the largest angle which is unwell worded but they are probably looking for the biggest angle of A

Wait sine theta/8.7 is solving for A, so why are they taking that away from 180 in the first place, that equals the sum of ABC + ACB no? Or am I just stupid.
I mean because the side that is 8.7cm is opposite to A
