The side against bigger angle is greatest.
So, R is against 70 degrees but S is against 80 degrees.
S>R
Option B

But there is another triangle in which R is opposite 90, how do we decide whether to consider R opposite to 70 or 90.
Clearly 90 is the greatest angle , so according to logic " side opp. greatest angle is greatest side" why cannot we say side R is the greatest.
