Answer:
Explanation:
Pre-Solving
We are given that J and L are collinear, meaning they are on the same line, and that K is between J and L.
We want to find the length of JK, and know that KL = 9 and JL = 17.
Recall that JL is the sum of KL and JK.
Solving
Since JL is the sum of KL and JK,
JL = KL + JK
Now, we can substitute the values we know into the equation.
17 = KL + 9
Subtract 9 from both sides.
8 = KL
