Final answer:
To find KL in the given figure, use the fact that JK + KL = JL. Substitute the given values, 8 and 23, and solve for KL.
Step-by-step explanation:
To find KL in the given figure, we need to use the fact that JK + KL = JL. We are given that JK = 8 and JL = 23. Substituting these values into the equation, we get 8 + KL = 23. Solving for KL, we subtract 8 from both sides to get KL = 15.
