Explanation:

Step1: Identify the triangle type

Since two angles are marked as equal (the angles at \(Y\) and \(W\) are congruent), the triangle is isosceles.

Step2: Apply the property of isosceles triangle

In an isosceles triangle, the sides opposite the equal angles are equal. The side opposite the angle at \(Y\) is \(XW = 19\), and the side opposite the equal angle (at \(W\)) is \(XY=u\).

Answer:

\(u = 19\)
