Final answer:
Angle a and angle b are complementary angles. Angle a measures 44°. The measure of angle b is 46°.
Step-by-step explanation:
Angle a and angle b are complementary angles, which means that the sum of their measures is 90°. Angle a measures 44°, so we can find the measure of angle b by subtracting 44° from 90°.
90° - 44° = 46°
Therefore, the measure of angle b is 46°.
