    Answer:

      adjacent angles are 50° and 130°

    Step-by-step explanation:

    The sum of all 4 angles in a parallelogram is 360°, so the fourth angle must be …

      360° -310° = 50°

    Adjacent angles are supplementary, so the other two angles must be …

      180° -50° = 130°

    The angles in the parallelogram are either 50° or 130°. Adjacent angles are different.
