Question

suppose m is the mid - point of $overline{jk}$. $jm=y + 4$, and $mk = 2y+2$. find $jk$.

Explanation:

Step1: Set JM = MK

$y + 4=2y + 2$

Step2: Solve for y

$y=2$

Step3: Find JM and MK

$JM=y + 4=2 + 4 = 6$, $MK=2y+2=2\times2 + 2=6$

Step4: Calculate JK

$JK=JM + MK=6+6 = 12$

Answer:

12
