Question

6. If KM is the perpendicular bisector of JL, find KL.Answer choices:109495610

Answer 1

From the perpendicular bisector therorem, wehave,

`JK=KL`

That is,

`\begin{gathered} 4x+9=11x-61 \\ 11x-4x=61+9 \\ 7x=70 \\ x=(70)/(7)=10 \end{gathered}`

Therefor, by putting x = 10, in the value of KL we have,

`11*10-61=110-61=49`

Thus, option B is correct.
