Question

What is the length of segment SR? ___units

Answer 1

Answer:

$SR=12\ units$

Step-by-step explanation:

we know that

Triangles RTS and QTS are congruent  by SAS postulate

so

SR=SQ

substitute the given values

$2x+8=8x-4$

Solve for x

$8x-2x=8+4$

$6x=12$

$x=2$

Find out the length of segment SR

$SR=2x+8$

substitute the value of x

$SR=2(2)+8=12\ units$
