Question

Can someone conirm if I'm right or not?

Answer 1

We know that
`WZ` is the diameter of circle, so
`\angle ZCW = 180^(\circ)`. By knowing that central angles have the same degree value as the arcs they form by intercepting the circle, we now know that arc
`ZRW = \angle ZCW = 180^(\circ)`. So, the arc
`ZWX=ZRW+WX=180^(\circ)+63^(\circ)=243^(\circ)`
