Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
There is a cyclic quadrilateral .
As we know that Sum of opposite angles of a cyclic quadrilateral is supplementary.
So, it becomes,
[tex]98^\circ+x=180^\circ\\\\x=180^\circ-98^\circ\\\\x=82^\circ[/tex]
Hence, the value of x is 82°.
Therefore, Option 'a' is correct.
