But how do I solve this question in an exam? Because I wouldn't be allowed to take this table with me and I don't think it is possible to remember this table. There is not a single question like this in the NCERT textbook. Though these questions are there in most of the guide books. So will it come in exams? If yes, then can you please suggest me how to solve it sir?

Expert Answer:

If the table is not allowed in the exam, then the question would have an additional information at the end of it in brackets.
They will provide the value in brackets as either (sin 19.47 = 0.3333) or (sin-10.3333 = 19.47)
