Assertion: In figure, if $XY$ is parallel to $PQ$, then the angles $x$ and $y$ are $70^\circ $ and $45^\circ $ respectively.
Reason:
Sum of angles of a triangle is $180^\circ $. - A
Both assertion and reason are true and reason is the correct explanation of assertion.
- B
Both assertion and reason are true but reason is not the correct explanation of assertion.
- C

- ✓
Assertion is false but reason is true.
AnswerCorrect option: D. Assertion is false but reason is true.
$\text{XY}\parallel\text{PQ}$ and EF is transversal
$\angle\text{EBQ}=\angle\text{EAY}$ (Corresponding angles)
$20^\circ + y = 60^\circ $
$y = 60^\circ - 20^\circ $
$y = 40^\circ $
Now, in $\triangle\text{ABD},$
$\text{x}+20^\circ=\angle\text{EAD}$ (External angle property)
$x + 20^\circ = 60^\circ + 35^\circ$
$x = 95^\circ - 20^\circ$
$x = 75^\circ$
