    77° or 103°

    Step-by-step explanation:

    All of the angles are either the given angle or its supplement. Corresponding angles are congruent, as are vertical angles. Any linear pair of angles will add to 180°.

    77° and 103°

    Step-by-step explanation:

    77° because it says one of the angles is 77°

    103° because two parallel lines are equal to 180°

    180°-77° is 103°
