Yes, they are a supplementary pair.

Answer 1

To determine if angles A and B are supplementary, we need to check if their measures add up to 180°.

Given:
- m∠A = 53°
- m∠B = 127°

Now, let's add them together:

53° + 127° = 180°.

Since the angles add up to 180°, they are supplementary.

Therefore, the correct response is:

**Yes, they are a supplementary pair.**
