MCQ
Supplementary angle of $100^\circ $ is:
- A$180^\circ $
- B$90^\circ $
- ✓$80^\circ $
- D$60^\circ $
✓
Answer
Correct option: C.
$80^\circ $
Supplementary angles are two angles that have a sum of $180^\circ .$
The given supplementary angle is $100^\circ $ and we have to find other.
$\Rightarrow $ Supplementary angle $= 180^\circ - 100^\circ = 80^\circ .$
$\therefore$ Supplementary angle of $100^\circ $ is $80^\circ .$
