Applying the exterior angles theorem, the measure of the exterior angle is: m∠2 = 139°.

What is the Exterior Angles Theorem?

The exterior angles theorem states that the measure of the two remote angles in a triangle is equal to the measure of the exterior angle of a triangle.

Thus:

75° and 64° are remote interior angles.

Therefore:

m∠2 = 75° + 64°

m∠2 = 139°
