The length of the line segment IJ is 9.
In this question we find that the line segments IJ and JK are collinear, that is, part of one same line. By Euclidean geometry and algebra, we construct the following formula:
IK = IJ + JK
IJ = IK - JK
If we know that IK = 19 and JK = 10, then the length of the missing line segment is:
IJ = 19 - 10
IJ = 9
The length of the line segment IJ is 9.
The statement is poorly formatted, correct form is shown:
The point J is on line segment IK. Given that JK = 10 and IK = 19, determine the length IJ.
