Answer:
16
Step-by-step explanation:
U is the midpoint of TV ⇒ TV = TU + UV
TU and UV equals each others since U is the midpoint of TV
- UV = TU ⇒ [tex]x+ 8 = 2x \\[/tex]
add -x to both sides
[tex]x + 8 -x = 2x - x \\8 = x \\x = 8[/tex]
- TU = [tex]x + 8[/tex] ⇒ TU = [tex]8 + 8[/tex] = [tex]16[/tex]
