    O is the center of the circle. Find the value of x, y, and z.

    Is 80 an angle measure, segment length, or what?

    I don't see how that 80 degree angle could actually be 80 degrees if it is located and correctly marked.

    An angle formed by a chord and a tangent on a circle has measure 1/2 its intercepted arc. So that arc would be 160.

    Assuming the the exterior segment is a tangent. It was not given to be.

    I see three congruent chords in the same circle. So they have congruent arcs.

    160*3 exceeds the number of possible degrees in a circle. So, I don't know what to write. Are you sure you posted all the given information?
