Answer:
[tex]TU = 1[/tex]
Explanation:
Given
[tex]TV = 3x[/tex]
[tex]UV = x + 1[/tex]
[tex]TU = x[/tex]
Required
Determine TU
Since U lies on TV, then
[tex]TV = TU + UV[/tex]
Substitute values for TV, TU and UV
[tex]3x = x + x + 1[/tex]
[tex]3x = 2x + 1[/tex]
Collect Like Terms
[tex]3x- 2x = 1[/tex]
[tex]x = 1[/tex]
Recall that [tex]TU = x[/tex]
Then
[tex]TU = 1[/tex]
