Plug in 6.5 for x.
-8.5x-3.5x=-78
-8.5(6.5)-3.5(6.5)=-78
-55.25-22.75=-78
-78=-78

Answer:
KL ≈ 1.94
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos48° = = = ( multiply both sides by KL )
KL × cos48° = 1.3 ( divide both sides by cos48° )
KL = ≈ 1.94 ( to the nearest hundredth )
