Answer:

  ∠B = 41°

Step-by-step explanation:

Step 1: Recognize that ∠B and ∠A are "remote interior angles" with respect to the exterior angle at C. Hence their sum will be equal to the measure of the exterior angle.

Step 2. Compute angle B as the difference between the exterior angle at C and the interior angle at A:

  113° - 72° = ∠B = 41°
