Final answer:
To find m ∠ BAH, subtract the measure of ∠HAC from 180°.
Step-by-step explanation:
To find m ∠ BAH, we need to understand the relationship between angles in a triangle. In a triangle, the sum of the measures of the angles is always 180°. So, if m ∠ HAC = 37°, then m ∠ BAH must be equal to 180° - m ∠ HAC. Substituting the given angle into the formula, we have m ∠ BAH = 180° - 37° = 143°. Therefore, the answer is D) 143°.
