Answer:
D. 12.5
Step-by-step explanation:
You can notice that ∠JMK and ∠JML are similar triangles.
That means that JM (from triangle on the left) is similar to KM (from triangle of the right)- the ratio between these must be:
[tex]\frac{6}{8}[/tex], that means that we can multiple KM (from triangle on the right) by this ratio to get ML (from triangle on the right).
[tex]6 * \frac{6}{8}=\frac{36}{8}=4.5[/tex]
Now we add JM to ML to to get JL - so 8 + 4.5 = 12.5
