Question

1.Find x
2.Find TU
3.Find UV

Answer 1

x = 6, TU = UV = 18

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
