ask something about it if you not got yet !
another method is this by eualising it .,-72+80-135/180=-72+80-135/180 ,,,-127/180=-127/180 ,they get cancelled to each other so 1=1 ..means left side is equal to right side . she it's proved now that they are equal to each other .
so please mark it as brainliest answer if you got it .
