Final answer:
The supplement of angle A cannot be determined from the given options without knowing the value of angle A.
Step-by-step explanation:
The supplement of angle A is the angle that, when added to angle A, results in a sum of 180 degrees. In this case, we are not given the value of angle A, so we cannot determine its supplement. The options provided in the question (295.90, 115.90, 25.99) are not valid supplements of angle A without knowing the value of angle A. Therefore, we cannot determine the correct answer from the options given.
