Answer: A

Explanation:

Since we know that T is the midpoint of SU, we know that it bisects SU. Now, we know that it cuts SU in half. With that, we know that ST and TU are equal.

3x=2x+20 [subtract both sides by 2x]

x=20

Now that we know x, we can plug them in to solve for each segment.

ST

3x [plug in x=20]

3(20) [multiply]

60

----------------------------------------------------------------------------------------------------------

TU

2x+20 [plug in x=20]

2(20)+20 [multiply]

40+20 [add]

60

----------------------------------------------------------------------------------------------------------

SU

60+60=120

We know that SU is ST and TU combines, therefore, we add the values of ST and TU.
