I got -30 and 19.5. I do think the sign is important as it indicates whether the angle is clockwise or anti-clockwise. I tried putting -19.5 and 30 into the calculator but they give sin with negative value.
you got -30 cause you did sin-1(-0.5) but, as you said, the negative is important IN GUIDING YOU.. that is to say, where the angle is negative.. like in the case of sin-1(1/3), the answer was 19.5 but you got positive value since it was sin-1 of 1/3 and not -1/3

Does anyone have the unofficial mark scheme?
There is no such thing as an unofficial marking scheme....but, the model answers solved by someone are above and they are usually fairly accurate
