Question

find the value of X and Y which ABC and XYZ are congruent. some problems may have more than one solution.

Answer 1

two triangles are congruentes when all sides measure the same

so first and second side are equals , just need than the third side are equal

then we match

`2x-1=4x-4`

and solve x

`\begin{gathered} -1+4=4x-2x \\ 3=2x \\ x=(3)/(2) \end{gathered}`

x is 3/2 and the third side measure 2

`\begin{gathered} 2((3)/(2))-1 \\ \\ =2 \end{gathered}`
