The angle shown in the picture appears to be 57 degrees. Since the question asks for the complementary or supplementary angle, we need to remember the following:
- Complementary angles add up to 90 degrees
- Supplementary angles add up to 180 degrees

To find the complementary angle, we subtract the given angle from 90 degrees: 90 - 57 = 33 degrees. Therefore, the complementary angle is 33 degrees.

To find the supplementary angle, we subtract the given angle from 180 degrees: 180 - 57 = 123 degrees. Therefore, the supplementary angle is 123 degrees.

Since the question is asking for either the complementary or supplementary angle, we could choose both answers A and C. However, since only one answer is asked for, the best choice is C, since it is the only one of the options provided. We cannot determine whether the given angle is complementary or supplementary based on the image provided. However, we do know that the sum of the angle and the unknown angle must add up to either 90° (complementary) or 180° (supplementary).

To find the unknown angle, we can subtract the given angle from 90° or 180° depending on whether it is complementary or supplementary.

90° - 57° = 33°

Therefore, the unknown angle is complementary and its measure is 33°.
