Dear Sayem. The A↔ B means that A is equivalent to B (in other words, A if and only if B). One takes only non-negative values of AB because the measure of the side cannot be negative and the value of sin C is also non-negative because C is an interior angle of the triangle (that is, it is less than 180 degrees), hence its sine cannot be negative.
in question 1 what do u mean by ↔ sign
