VS is the midpoint of trapezoid RTUW. If UT = 10 and VS = 18, what is WR?

To find WR, we need to first find the length of RU.

Since VS is the midpoint of trapezoid RTUW, then the length of RU is equal to the length of ST.
Since VS = 18 and UT = 10, ST = VS - UT = 18 - 10 = 8.

Since RU = ST = 8, and UT = 10, then WR = RU + UT = 8 + 10 = 18.

Therefore, WR = 18.
