  y = 32°

Step-by-step explanation:

Angle y is one of two congruent base angles in the isosceles triangle BCD that has angle B as its third angle:

  2y + 116° = 180° . . . . . . . sum of angles in a triangle

  y + 58° = 90° . . . . . . . . divide by 2

  y = 32° . . . . . . . . . . . . subtract 58°

To those of you copying this the question here asks for angle y. The other variables can be found from ...

  x = 2y = 64° . . . . . . . the arc is twice the measure of the inscribed angle

  z = ∠CBD = 116°
