x=

Explanation:

Step1: Determine similar triangles

Since \(AB\parallel ED\), \(\triangle ABC\sim\triangle EDC\) (by AA similarity: \(\angle ABC=\angle EDC\) and \(\angle BAC=\angle DEC\) as alternate - interior angles).

Step2: Use the property of similar triangles (corresponding sides are proportional)

For similar triangles \(\triangle ABC\) and \(\triangle EDC\), we have the proportion \(\frac{AB}{ED}=\frac{AC}{EC}=\frac{BC}{DC}\).
Given \(AB = 11\), \(ED=44\), \(AC = 6\), \(BC = 4\).
Let's first find \(n\) (corresponding to \(BC\) and \(n\) with \(AB\) and \(ED\)):
\(\frac{AB}{ED}=\frac{BC}{n}\), substituting the values \(\frac{11}{44}=\frac{4}{n}\).
Cross - multiply: \(11n=4\times44\), so \(n=\frac{4\times44}{11}=16\).
Now find \(x\) (corresponding to \(AC\) and \(x\) with \(AB\) and \(ED\)):
\(\frac{AB}{ED}=\frac{AC}{x}\), substituting the values \(\frac{11}{44}=\frac{6}{x}\).
Cross - multiply: \(11x = 6\times44\), so \(x=\frac{6\times44}{11}=24\).

Answer:

\(n = 16\), \(x = 24\)
