Answer:
The measure of arc ZWX is [tex]230\°[/tex]
Step-by-step explanation:
we know that
The diameter divide a circle into two equal parts
so
[tex]arc\ ZWX=arc\ ZRW+arc\ WX[/tex]
we have
[tex]arc\ ZRW=180\°[/tex] ----> because WZ is a diameter
[tex]arc\ WX=50\°[/tex]
substitute
[tex]arc\ ZWX=180\°+50\°=230\°[/tex]
