Final answer:
The measure of the other complementary angle is 70.25°, since the sum of complementary angles is always 90 degrees.
The correct option is c.
Step-by-step explanation:
The question relates to the concept of complementary angles in geometry. Two angles are said to be complementary if the sum of their measures is 90 degrees.
If one angle measures 19.75°, then to find the measure of the other angle, we subtract the given angle from 90 degrees.
90° - 19.75° = 70.25°
Therefore, the degree measure of the other angle is 70.25°, which corresponds to choice c in the multiple choice options provided.
