Answer:
z=104
Step-by-step explanation:
A line is always 180 degrees.
This model is formed by 2 lines.
z and 76 form a line, which means that they are supplementary.
We can set up this equation:
z+76=180
Subtract 76 from both sides.
z=104
If you needed to figure out x, it would also be 104 degrees.
This is because x and z are vertical angles.
Vertical angles are always congruent.
