Answer:

Step-by-step explanation:

If two triangles are congruent, then every corresponding part of one triangle is congruent to the other. Therefore,

[tex]\begin{gathered} m<\text{DCB}=m<\text{BCA} \\ m<\text{DBC}=m<\text{CBA} \\ \text{Then,} \\ 5x=3y+11 \\ 3x+10=y+7 \end{gathered}[/tex]

Now, re-order the two equations and solve the system of linear equations:

[tex]\begin{gathered} 5x+3y=11\text{ (1)} \\ 3x-y=-3\text{ (2)} \end{gathered}[/tex]

Isolate y from equation (2) and substitute it into equation (1):
