Explanation:

Step1: Use the property of isosceles triangle

In a triangle, if two angles are congruent (\(\angle S\cong\angle U\)), then the sides opposite those angles are congruent.

Step2: Identify the sides

In \(\triangle STU\), the side opposite \(\angle S\) is \(TU\), and the side opposite \(\angle U\) is \(ST\). Since \(\angle S\cong\angle U\), we have \(ST = TU\).

Step3: Substitute the given value

Given \(TU = 20\), so \(ST=20\).

Answer:

\(20\)
