Answer:
Because of the parallel lines, the angle directly below y is 76° (corresponding angles).
Adjacent angles on a straight line add up to 180°.
y = 180 - 76 = 104°
There are two ways to find z.
Method 1:
Since (6z - 110)° and y is on the same line,
(6z - 110) + 104 = 180
6z - 6 = 180
6z = 186
z = 31°
Method 2:
Since angle below y is 76°,
6z - 110 = 76 (vertically opposite angles)
6z = 186
z = 31°
