Math Problem Statement
Solution
The diagram shows two parallel lines and that are intersected by a transversal . We are given that , and the goal is to determine the measure of .
Key observations:
- implies that angles formed by the transversal will have special relationships such as corresponding angles, alternate interior angles, and consecutive interior angles.
- is an exterior angle with respect to the parallel lines and the transversal.
- is an alternate interior angle with , since they are on opposite sides of the transversal and between the two parallel lines.
Relationship of angles:
For two parallel lines, alternate interior angles are congruent. Thus:
Therefore, .
