    For "Untitled" you need to know that when you have parallel lines cut by a traversal:

    - Alternating (Z) angles are equal

    - Corresponding (F) angles are equal

    - Opposite (X) angles are equal

    - Cointerior (U or C) angles add to 180 degrees

    - Angles in a circle add to 360 degrees.

    There are two sets of parallel lines. You should be able to see Z angles formed from the horizontal parallel lines. The rest falls together from there.
