MCQ
The angles $x – 10^\circ $ and $190^\circ – x$ are:
- AInterior angles on the same side of the transversal.
- BMaking a linear pair.
- CComplementary.
- ✓Supplementary.
✓
Answer
Correct option: D.
Supplementary.
Sum of the given angles.
$= (x - 10^\circ ) + (190^\circ - x) = x - 10^\circ + 190^\circ – x$
$= (x - x) + (190^\circ - 10^\circ ) = 0 + 180^\circ = 180^\circ $
Since, the sum of given angles is $180^\circ ,$
Hence, they are supplementary.
$= (x - 10^\circ ) + (190^\circ - x) = x - 10^\circ + 190^\circ – x$
$= (x - x) + (190^\circ - 10^\circ ) = 0 + 180^\circ = 180^\circ $
Since, the sum of given angles is $180^\circ ,$
Hence, they are supplementary.
