Use the image to answer the question.
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 ?

To find the measure of angle 2, we can use the fact that angles 1 and 2 together form a right angle. Since a right angle is always 90 degrees, we can subtract the given measure of angle 4 from 90.
Therefore, 90 - 31 = 59.
Hence, m∠2 = 59°.
