Final answer:
Without additional information about the relationship between ∠A and ∠B, we cannot determine the measure of ∠B. If ∠A and ∠B are supplementary, then ∠B would be 118°.
Step-by-step explanation:
The subject of this question is Mathematics, specifically, it deals with understanding angles and their measurements. If given ∠A = 62°, we need to find the measure of ∠B. Without additional context, such as a diagram or further information about the relationship between ∠A and ∠B, it's impossible to assert a factual answer. However, if we were to assume ∠A and ∠B are supplementary angles (which add up to 180°), then ∠B would be 180° - 62° = 118°, which corresponds to option b). If no such relationship is implied, one cannot determine the measure of ∠B without further information.
