In the real world you draw a pencil line on the chart, measure the angle in degrees (true) then apply the magic (TVMDC+W) to find what number you want to look at in the cockpit.
And, as already pointed out, as you can't fly to 2 degrees accuracy, and as you can't usually measure the angle on the chart to 2 degrees accuracy, if there are two multiple choice answers which differ by 2 degrees the correct answer is "who cares?".
