MCQ
In the adjoining figure, l || m then $\angle\text{x}$ is equal to:
- ✓$56^\circ$
- B$51^\circ$
- C$66^\circ$
- D$61^\circ$
✓
Answer
Correct option: A.
$56^\circ$
$x + 51^\circ = 107^\circ $ (Alternate interior angles)
$x = 107^\circ - 51^\circ = 56^\circ .$
$x = 107^\circ - 51^\circ = 56^\circ .$
