The three red curved bands for angles Y and Z tell us that angle Y is congruent to angle Z

So you can say Y = Z

jim_thompson5910 · Answer

`W+X+Y+Z = 360` because for ANY quadrilateral (figure with 4 sides), the 4 angles always add to 360 degrees

jim_thompson5910 · Answer

so,

W+X+Y+Z = 360

129+79+Y+Z = 360 ... plug in the values for X & W

129+79+Z+Z = 360 ... replace Y with Z (since Y = Z)

now solve for Z
