Answer:
x=-8
Explanation:
The given triangle has three equal sides. This type of triangle is called an Equilateral Triangle.
In an Equilateral triangle, all the angles are usually equal, i.e. each angle is 60 degrees.
Therefore:
[tex]\begin{gathered} m\angle2=60\degree \\ \implies x+68=60\degree \\ x=60-68 \\ x=-8 \end{gathered}[/tex]
The value of x in the triangle is -8.
