Question

Point J is on line segment IK. Given IK = 15 and JK = 6, determine the length IJ.

Answer 1

Answer:

$\huge\boxed{IJ = 9}$

Step-by-step explanation:

Given that J is on line segment IK.

So, it is like:

I______?_______J___6___K

|<--------------------15---------------->|

We know that:

IK = IJ + JK

Where IK = 15 and JK = 6

15 = IJ + 6

Subtracting 6 to both sides

IJ = 15 - 6

IJ = 9
