Answer:
Explanation:
We can start by using the fact that TV = TU + UV. Substituting the given values, we have:
TV = TU + UV
(3x - 17) = (x + 3) + 18
Simplifying and solving for x:
3x - 17 = x + 21
2x = 38
x = 19
Now that we have the value of x, we can find TU using the given equation:
TU = x + 3
TU = 19 + 3
TU = 22
Therefore, TU = 22 units.
