Math Problem Statement
Solution
The problem presented involves a pair of parallel lines cut by a transversal, and the task is to find the value of .
Based on the diagram:
- We have two parallel lines, denoted by the parallel symbol ().
- A transversal line intersects the parallel lines, creating various angles.
- The given angle measures are:
- An angle of at the top intersection of the transversal.
- An angle of and at the bottom intersection.
Explanation:
-
Corresponding Angles: The angle at the top intersection is corresponding to the angle at the bottom because corresponding angles are congruent when a transversal cuts two parallel lines.
Therefore: Solving for :
Thus, the value of is .
