If Lines AB||CD, then e = ?

Explanation

When two lines, such as AB and CD, are parallel, and a transversal crosses them, the angles on the same side of the transversal are supplementary. This means their measures add up to 180°. Given one angle is 69°, the supplementary angle, denoted as e, is calculated as 180° - 69° = 111°. Therefore, e = 111° is the correct answer. Option A and C provide incorrect values, and Option D is invalid as Option B already provides the correct answer.
