An illustration shows five rays emerging from an unlabeled point, forming the following angles from left to right: 1, 2, 3, 4, and 5. Angles 1 and 2 together form a right angle.
If m∠4=31° , what is m∠2 ?

180°
59°
90°
31°
If angles 1 and 2 together form a right angle, then angle 1 must be 90°.
Since angle 4 is given as 31°, the sum of angles 1, 2, 3 and 4 must be 180°.
So, m∠2 = 180° - 90° - 31° = 59°.
Therefore, the answer is 59°.
