Answer ⤵️
By changing the order of vertices,
We have four conditions,
When we have or ,
Then by the property of similar angles,
⇒
⇒
⇒
⇒
⇒ x = 2
But, or is given,
Then by the property of similar triangles,
⇒
⇒
⇒
⇒
⇒ x = 17
Note: is reflexive angle in both triangles this is why, in each condition we took A is corresponding to A.

Answer: here it is
Step-by-step explanation:
If abe is similar to acd, sf= 18/15
SF=1.2
AC=1.2 times 10= 12
12-10=2
x=2cm
If abe is similar to adc, sf= 18/10
SF= 1.8
AC= 1.8 times 15= 27
27-10=17
x= 17cm
