The theorem is used to prove △ABC≅△DEC is Side-Angle-Side(SAS) theorem
The two triangles are
△ABC and △DEC
Here we have to prove that the △ABC and △DEC are congruent
It is given that
The length of AC = The length of CD
The angle ACB = The angle ECD
The point C is the midpoint of EB
Therefore,
The length of BC = The length of EC
Therefore, the two sides and one angle of triangle ABC is equal to the two sides and one angle of triangle DEC, so the both triangles are congruent by SAS rule
Hence, the theorem is used to prove △ABC≅△DEC is Side-Angle-Side(SAS) theorem.

Answer:
"X"= 2
Step-by-step explanation:
1. combain like terms in the equation.
2. then divide both sides by what you get after combining which could be "82".
3. then 82 divide by 82 is 0, then "x"will remain.
4. then 243 ÷ 82=2.
5. then X =2.
