Math Problem Statement

In the figure, a pair of parallel lines intersected by a transversal creates angle relationships. Find the value of x.

Solution

The problem presented involves a pair of parallel lines cut by a transversal, and the task is to find the value of xx.

Based on the diagram:

  • We have two parallel lines, denoted by the parallel symbol (\parallel).
  • A transversal line intersects the parallel lines, creating various angles.
  • The given angle measures are:
    • An angle of 130130^\circ at the top intersection of the transversal.
    • An angle of 4x4x^\circ and 2x2x^\circ at the bottom intersection.

Explanation:

  1. Corresponding Angles: The angle 130130^\circ at the top intersection is corresponding to the angle 4x4x^\circ at the bottom because corresponding angles are congruent when a transversal cuts two parallel lines.

    Therefore: 4x=1304x = 130 Solving for xx: x=1304=32.5x = \frac{130}{4} = 32.5

Thus, the value of xx is 32.532.5^\circ.
