I don't have the triangle or the side lengths from the problem, so I can't pick one of the choices directly. Please either paste the diagram or tell me the lengths of the opposite and adjacent sides for angle A.
How to do it once you have the side lengths:
1. Compute the ratio opposite/adjacent.
2. Use your calculator's inverse tangent (tan^(-1) or arctan) on that ratio (make sure your calculator is in degree mode).
3. Round the result to the nearest whole degree.
Example: if opposite = 3 and adjacent = 4, A = arctan(3/4) ≈ 36.87°, so A ≈ 37°.
