Geometry proof. will mark as brainliest.
list the reasons that go with each statement to prove δabc ∼ δgef. (10 points)

statements
1) ∠abc≅∠dec
2) ∠gfe≅∠dce
3) ∠bca≅∠dce
4) ∠gef≅∠dec
5) ∠abc≅∠gef
6) ∠gfe≅∠bca
7) δabc ~ δgef

1. < DCE=< DEC in the picture
⇒<ABC=<DEC=< DCE=<BCA  ⇒ the triangle ABC is isosceles

 2. ⇒<GFE=<DCE=<DEC=<FEG ⇒ the triangle EFG is isosceles 
⇒ the triangles ABC and EFG have 2 angles equals ⇒ ABC~ EFG

5. ⇒ < ABC=<GEF =<DEC= < DCE=< BCA ⇒ the triangle ABC is isosceles
6. < GFE = < BCA= < ECD = <DEC = <FEG ⇒ the triangle EFG is isosceles

⇒ the triangles ABC and EFG have 2 angles equals ⇒ ABC~ EFG 

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3

1/5 i hope this
