Answer:
139 degrees
Step-by-step explanation:
Hello, and welcome to Brainly!
As you'll likely recall, the sum of all the interior angles of a triangle is 180 degrees. Let's sum up the two given angles: 75 + 64 = 139 (degrees). Thus, the third interior angle is 180 - 139 (degrees), or 41 degrees.
Now, this 41-degree angle and angle 2 are "straight angles;" they add up to 180 degrees. To find angle 2, subtract 41 from 180: 139. Thus, the measure of angle 2 is 139 degrees.
