find the value of x.
6
x
x=
1 2 3 4 5 6 7 8 9

Explanation:

Step1: Use the property of isosceles triangles

In an isosceles triangle, the sides opposite equal angles are equal. Here, the two triangles are congruent (by SAS - Side - Angle - Side congruence as the common side, equal marked angles and the equal sides with tick marks). So the side \(x\) is equal to the side of length \(6\).

Answer:

\(6\)
