Answer: 126

Explanation:

The inside angles of any triangle always add to 180 degrees.

x+80+46 = 180

x+126 = 180

x = 180-126

x = 54

Then we'll use the fact angles x and y are supplementary.

x+y = 180

54 + y = 180

y = 180-54

y = 126

-------------

Shortcut: Use the remote interior angle theorem to add the known interior angles 80 and 46 to get 80+46 = 126 as the exterior angle that is not adjacent to those interior angles.

y=126
angles in a rectangle add to 180 so 80+46=126 180-126=54 x=54
x is equal to the angle opposite and we can find z by doing 180-54 since angles on a straight line add up to 180 so that would be 126 and since y is vertically opposite to z it would also be 126 degrees
