Answer:
SAS theorem
Step-by-step explanation:
If
and m∠ECD = m∠BCA, then the triangles are similar by the SAS theorem.

So,
and m∠ECD = m∠BCA because vertical angles are congruent
Therefore ΔECD is similar to ΔBCA by SAS theorem
1369. If this is what you are trying to find, hope this helps.
I pretty sure you would use x over 38.00 = 20 over 100 then cross multiply them
