Question

In the given figure, O is the centre of the circle. Find the value of $X$.

$\left[1\right]$

Answer 1

In the given figure, $\angle ABD={50}^{\circ }$

Since the angles subtended by an arc in the same segment are equal, we have $\angle ABD=\angle ACD.$
$\left[1\right]$


$\Rightarrow X=\angle ACD={50}^{\circ }$

$\left[1\right]$
