Answer:
[tex]TU=10\ units[/tex]
Step-by-step explanation:
we know that
Point T is on line segment SU (between point S and point U)
so
[tex]SU=ST+TU[/tex]-----> by addition segment postulate
substitute the given values and solve for x
[tex]5x+1=(4x-4)+(4x-10)[/tex]
[tex]5x+1=8x-14[/tex]
[tex]8x-5x=1+14[/tex]
[tex]3x=15[/tex]
[tex]x=5[/tex]
Find the length of TU
[tex]TU=4x-10[/tex]
substitute the value of x
[tex]TU=4(5)-10[/tex]
[tex]TU=10\ units[/tex]
