Answer:

[tex]SR=12\ units[/tex]

Step-by-step explanation:

we know that

Triangles RTS and QTS are congruent  by SAS postulate

so

SR=SQ

substitute the given values

[tex]2x+8=8x-4[/tex]

Solve for x

[tex]8x-2x=8+4[/tex]

[tex]6x=12[/tex]

[tex]x=2[/tex]

Find out the length of segment SR

[tex]SR=2x+8[/tex]

substitute the value of x

[tex]SR=2(2)+8=12\ units[/tex]
