To find the measure of angle 2, we need to know that angles 1 and 2 form a right angle, which means they add up to 90 degrees. Since angle 4 is given as 31 degrees, we can subtract angle 4 from 90 degrees to find angle 2:
m∠2 = 90° - 31° = 59°
Therefore, m∠2 is 59 degrees.
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 ?
