Verified Answer :

Triangles ADE and ABC are similar, so their legs are proportional to one another. Let \(x\) be the length of AE. You have

\(\dfrac{AD}{AE}=\dfrac{AB}{AC}\implies\dfrac6x=\dfrac7{x+3}\)

Solve for \(x\).

\(\dfrac6x=\dfrac7{x+3}\)
\(6(x+3)=7x\)
\(6x+18=7x\)
\(x=18\)

So the length of AE is 18.

Considering that triangle ADE and ABC in the diagram given are similar, the length of AE is: 18.

Recall:

  • Two triangles that are similar have corresponding sides that are congruent to each other as they have same shape.

Triangles ADE and ABC are similar.

  • Therefore:

AD/AB = AE/AC

AD = 6 in.

AB = 6 + 1 = 7

AE = ?

AC = AE + 3

  • Substitute

\(\frac{6}{7} = \frac{AE}{AE + 3}\)

  • Cross multiply

\(6(AE + 3) = (7)(AE)\\\\6AE + 18 = 7AE\\\\\)

  • Collect like terms

\(6AE + 18 = 7AE\\\\18 = 7AE - 6AE\\\\18 = AE\\\\\mathbf{AE = 18}\)

Therefore, considering that triangle ADE and ABC in the diagram given are similar, the length of AE is: 18.
