Complementary angles are two angles whose measures add up to 90 degrees.
Let's evaluate each pair:
a. 42° and 58°:
42° + 58° = 100° (not complementary)
b. 100° and 80°:
100° + 80° = 180° (not complementary)
c. 38° and 52°:
38° + 52° = 90° (complementary)
d. 300° and 60°:
300° + 60° = 360° (not complementary)
The only pair that is complementary is:
**c. 38° and 52°**.
