Answer to Question #141295 in Geometry for janae

Question

R is the midpoint of PS.Q is the midpoint of PR. PR=3. what is the length of QS

Answer 1

$R$ is the midpoint of $PS$ .

$Q$ is the midpoint of $PR.$ .

$PR=RS=3$

$QR=\frac{1}{2}PR$

So,

$QR=\frac{1}{2}×3=1.5$

$PR=RS$

therefore,

$PR=RS=3$

$QS=QR+RS$

$QS=1.5+3=4.5$

$QS=4.5(Answer)$
