The information about the angles shows that:
- Complementary to 40° = 50°
- Complementary to 67° = 23°
- Supplementary to 80° = 100°
- Supplementary to 65° = 115°
What are complementary angles?
It should be noted that complementary angles refers to the angles that are equal to 90°. On the other hand, supplementary angles are the angles that are equal to 180°.
The complementary to 40°:
= 90° - 40°
= 50°
The complementary to 67° will be:
= 90° - 67°
= 23°
The supplementary to 80° will be:
= 180° - 80°
= 100°
The supplementary to 65° will be:
= 180° - 65°
= 115°
