MCQ
Mark $(\checkmark)$ against the correct answer: In the given figure, $\ce{AOB}$ is a straignt line, $\angle\text{AOC}=56^\circ$ and $\angle\text{BOC}=\text{x}^\circ$ The value of $x$ is:
- A$34$
- B$44$
- C$144$
- ✓$124$
✓
Answer
Correct option: D.
$124$
$x^\circ + 56^\circ = 180^\circ ($linear pair$)$
$\Rightarrow x^\circ = 180^\circ - 56^\circ$
$\Rightarrow 124^\circ$
$\therefore x = 124$
$\Rightarrow x^\circ = 180^\circ - 56^\circ$
$\Rightarrow 124^\circ$
$\therefore x = 124$
