Step 1: Understanding Complementary Angles.
Complementary angles are two angles that add up to 90°.
Step 2: Verifying the Options.
- Option (1): 40° + 30° = 70°, not complementary.
- Option (2): 60° + 55° = 115°, not complementary.
- Option (3): 30° + 60° = 90°, making this the correct answer as the angles are complementary.
- Option (4): 20° + 60° = 80°, not complementary.
Conclusion:
Therefore, the correct answer is (3) 30° and 60°.
