Answer:
KL = 10
Step-by-step explanation:
Point K is on line segment \overline{JL} JL . Given
JK=2x−2
JL=2x+8
KL=x-9
JL = JK + KL
Hence:
2x + 8 = 2x - 2 + x - 9
2x + 8 = 2x + x - 2 -9
2x + 8 = 3x - 11
Collect like terms
3x - 2x = 8 + 11
x = 19
We are to find the numerical length of KL
KL = x - 9
KL = 19 - 9
KL = 10
