Answer:
To find the value of SU, we need to examine the given information about ST, TU, and Y.
We know that ST = 2 and TU = 2x, where x represents an unknown value. Additionally, Y = x + 5.
To find SU, we can break it down into two parts: ST + TU.
Substituting the given values, we have:
SU = ST + TU
= 2 + 2x
Therefore, the value of SU is 2 + 2x.
