The numerical length of the line segment ST is 3.
<h3>What is the numerical length of a line segment?</h3>
Herein we have a line segment formed by three points collinear to each other. Mathematically speaking, we find the following condition:
SU = ST + TU
4 · x = (2 · x + 1) + (5 · x - 4)
4 · x = 7 · x - 3
3 · x = 3
x = 1
And the numerical length of the line segment ST is:
ST = 2 · 1 + 1
ST = 3
The numerical length of the line segment ST is 3.
