I currently dont have a calculator on me but this would give you the answer :)
Be aware that if you are given the values of two sides and an angle OR two angles and one side of a triangle, they are likely testing you on sine rule

I suspect this could be a “construct accurately a diagram” question rather than a sine rule question since the sine rule is only used in Sec 3 and considering the fact that this question is posted as a Sec 2 question at the start of the year, I presume that the student has yet to experience trigonometry or the Pythagorean formula.
EDIT: I see a circular scratch on the piece of paper that the student has posted, so I’m quite certain it’s a construction question.
