Question

Given that R is between Q and T QT=9 RT=3 Find QR

Answer 1

the value of QR is 6;

Given that R is between Q and T;

Then;

`QT=QR+RT`

Given;

`\begin{gathered} QT=9 \\ RT=3 \end{gathered}`

Substituting the given values;

`\begin{gathered} QT=QR+RT \\ 9=QR+3 \end{gathered}`

Subtracting 3 from both sides;

`\begin{gathered} 9-3=QR+3-3 \\ 6=QR \\ QR=6 \end{gathered}`

Therefore, the value of QR is 6;

`QR=6`
