Respuesta :

the answer for your question is x= -3/2

The inequality to find the possible values of [tex]x[/tex] is required.

The solution is [tex]x>-1.5[/tex]

[tex]AB=BC=DC=2x[/tex]

[tex]AC=AB+BC=2x+2x\\\Rightarrow AC=4x[/tex]

In a triangle the sum of any two sides is greater than the third side

So,

[tex]AC+DC>AD[/tex]

[tex]\Rightarrow 4x+2x>4x-3[/tex]

[tex]\Rightarrow 6x>4x-3[/tex]

[tex]\Rightarrow 2x>-3[/tex]

[tex]\Rightarrow x>-\dfrac{3}{2}[/tex]

[tex]\Rightarrow x>-1.5[/tex]
