Answer: x = 112°, z = 31°
Explanation:
We can find the measurement of angle x since ∠x and 68° are same-side interior angles and they are supplementary.
180° - 68° = x
112° = x
x = 112°
Next, we can find the measurement of angle x because of the corresponding angles and vertical angles.
x = (4z - 12)
112° = (4z - 12°)
124° = 4z
z = 31°
