SUMMARY
The angle in question is considered 90 degrees due to the geometric relationships established by the line segments. Specifically, line segment CE is parallel to line segment AB, and line segment AD is perpendicular to AB at point A. Consequently, this makes line segment AD also perpendicular to line segment EC at point E, confirming that the angle formed is indeed 90 degrees.
