Answer:
x = 6, TU = UV = 18
Step-by-step explanation:
Since U is the midpoint of TV , then
UV = TU , substitute values
5x - 12 = 3x ( subtract 3x from both sides )
2x - 12 = 0 ( add 12 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Thus
TU = 3x = 3(6) = 18
UV = 5x - 12 = 5(6) - 12 = 30 - 12 = 18
