139 degrees is probably right... I did it in my head so u mighr want to check

Answer:

139°

Step-by-step explanation:

By definition, the measure of an exterior angle is the sum of the two interior angles not supplementary to the exterior one.

Here, we see that the two interior angles not supplementary to ∠2 are valued at 75° and 64°, so our exterior angle is the sum of these:

∠2 = 75 + 64 = 139°
