Mark $(\checkmark)$ against the correct answer: In the given figure, $AOB$ 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 $
$\therefore x = 124$
