Answer:

  • Inscribed angle is half of the intercepted arc.
  • Central angle is the same size as the intercepted arc.

As per above two statements we have:

  • y = 2*58° = 116°

and

  • z = 90°/2 = 45°

Answer:

y=58×2=116 central angle of the cyclic quadrilateral is double if inscribed angle

z=90/2=45

inscribed angle is half of central angle of the cyclic quadrilateral
