In the given figure, if
then 

- 110°
- 20°
- 135°
- 70°
Hint:
In this question, we have to find the
ABC. Given that AB and PQ are parallel and QR and BC are parallel. Using the prallel lines theorem we can find the required angle.
The correct answer is: 70°

PQ is parallel to AB and QR is the transversal
Also, QR is parallel to BC and AB is the transversal.
= 
As angles are alternate interior angles so the angles are equal.
