The measure of the segment JK from the given information is 7
Line segment
A line is defined as the smallest distance between two points. The point where two lines meet is known as an angle.
Given the following parameters
JL=19 and KL=12
Required
Length of JK
Using the addition postulate
JK + KL = JL
JK + 12 = 19
Subtract 12 from both sides
JK + 12 -12 = 19 - 12
JK = 19-12
JK = 7
Hence the measure of the segment JK from the given information is 7
