											Answer:
The value of x is 66 .
Step-by-step explanation:
As given the figure in the question .
Sides of the two triangles are equal .
By using the property if two sides are equal there opposite angles are also equal .
Now by apply angle sum property of a triangle .
48 + x + x = 180°
2x = 180 - 48
2x = 132
[tex]X= \frac{132}{2}[/tex]
x = 66
Therefore the value of x is 66 .
