We will use the Thales theorem since ED and CB are parallel and A,D and B are in the same lign wich is the same for C,E and A

  • [tex]\frac{x}{12}[/tex] = [tex]\frac{2}{2+4}[/tex]
  • [tex]\frac{x}{12}[/tex] = [tex]\frac{2}{6}[/tex]
  • [tex]\frac{x}{12}[/tex] = [tex]\frac{1}{3}[/tex]
  • x= [tex]\frac{12*1}{3}[/tex]
  • x= 4

  • 2

since we have two similar sides and one similar angle between them it will be SAS similarity
