Answer:
x=24 inches
Explanation:
From the given information, consider ABCDE be the bow shaped polygon created by two segments intersecting forming two triangles with vertical angles that is ∠ACB=∠DCE.
AB=5 in, AC=8 in , CE=x inches and DE= 15 inches.
Now, From ΔABC and ΔDCE,
∠ACB=∠DCE(Vertically opposite angles)
∠BAC=∠DEC(Alternate angles)
Therefore, by AA similarity, ΔABC is similar to ΔDCE.
Thus, by using Proportionality theorem, we get
