Question

Point T is on line segment SU. Given ST=13 and TU=5, determine the length SU.

Answer 1

Answer:

We are given the lengths of the two segments of the line. Using the addition postulate we can obtain the segment of the entire line.

Did you draw out the diagram. We know that the three points are collinear.

Hope this helps

Answer 2

Answer:

$SU=18$

Step-by-step explanation:

The segments ST and TU make up the line segment SU. Add the values to find SU:

$ST+TU=SU\\\\13+5=18$

The length of SU is 18.
