Question

ST = N R In the figure below, S is between Q and I, and R is the midpoint of QS. If RS-5 and QT=17, find ST. S T X 6 S 7​

Answer 1

Answer: ST = 6

Explanation:

the segment sum is...

QR + RS + ST = QR

QR + 2 + ST= 10... use given values

Since R is the midpoint of QS, we know QR = RS = 2. Now, we have...

ST = 10 -2 -QR = 10 -2 -2 = 6

The length of ST is 6.
