Answer:
[tex]198^{\circ}[/tex]
Explanation:
We were given the information:
Line WZ and line XR are diameters of circle C
We will obtain the measure of ZWX as shown below:
[tex]\begin{gathered} ZWX=ZRW+WX \\ ZRW=180^{\circ}(straight\text{ }line) \\ WX=18^{\circ} \\ ZWX=180+18 \\ ZWX=198^{\circ} \end{gathered}[/tex]
Therefore, the correct option is the third option
