In a right triangle, the sum of the two acute angles is always 90 degrees because the right angle is 90 degrees and the remaining angles must add up to 90 degrees.
Given that one acute angle is 44°, we can find the measure of the other acute angle by subtracting 44° from 90°:
90° - 44° = 46°
Therefore, the measure of the other acute angle is 46°.
