MCQ
In fig if $x = 30^\circ $ then $y =$
- A$210^\circ$
- B$180^\circ$
- C$90^\circ$
- ✓$150^\circ$
✓
Answer
Correct option: D.
$150^\circ$
$x + y = 180^\circ $ (linear pair)
$x = 30^\circ$
$30^\circ + y = 180^\circ$
$y = 180^\circ - 30^\circ$
$y = 150^\circ .$
$x = 30^\circ$
$30^\circ + y = 180^\circ$
$y = 180^\circ - 30^\circ$
$y = 150^\circ .$
