From the given information, we know that angles 1 and 2 together form a right angle. Since angle 1 is a right angle, it measures 90°. Angle 4 is given as 31°. Angle 2 can be found by subtracting the sum of angles 1 and 4 from 180°, since the sum of the angles in a straight line is 180°.

Therefore, m∠2 = 180° - (90° + 31°) = 180° - 121° = 59°.

So, the correct answer is 59°.
