question 6 of 28
tx is the perpendicular bisector of su. what is the length of su?
a. 10
b. 20
c. 26
d. 24

Explanation:

Step1: Recall property of perpendicular bisector

Since $\overline{TX}$ is the perpendicular bisector of $\overline{SU}$, it divides $\overline{SU}$ into two equal - length segments. So $SX = XU$.

Step2: Calculate length of $\overline{SU}$

Given $XU = 10$, then $SX=10$. And $SU=SX + XU$. Substituting the values, we get $SU=10 + 10=20$.

Answer:

B. 20
