To find the value of \( x \) when given that lines \( \ell \) and \( m \) are parallel, we typically need additional information, such as the relationships between angles formed by a transversal intersecting the two lines.
Common scenarios might involve angles such as corresponding angles, alternate interior angles, or same-side interior angles, which can be set equal to each other based on the properties of parallel lines.
Please provide the diagram or details regarding the angles or equations related to lines \( \ell \) and \( m \) so I can assist you further in finding the value of \( x \).
