Let's start by identifying the hypotenuse of the triangle and the sides that are opposite and adjacent to ∠J.
We see that the length of the hypotenuse is 4sqrt(2). The length of the side adjacent to ∠J is 2sqrt(2) and the length of the side opposite to ∠J is 2sqrt(6). With this information, we can find the desired ratios.

Value
sin J
Length of leg opposite to∠J/Length of hypotenuse
2sqrt(6)/4sqrt(2)=sqrt(3)/2≈ 0.87
cos J
Length of leg adjacent to∠J/Length of hypotenuse
2sqrt(2)/4sqrt(2)=0.50
tan J
Length of leg opposite to∠J/Length of leg adjacent to∠J
2sqrt(6)/2sqrt(2)=sqrt(3)≈ 1.73
Ratios for ∠L
We already know the length of the hypotenuse is 4sqrt(2). Let's identify the sides that are opposite and adjacent to ∠L.
The length of the side adjacent to ∠L is 2sqrt(6) and the length of the side opposite to ∠L is 2sqrt(2). With this information, we can find the desired ratios.

In case you want to see the steps we took to rationalize the denominators of our ratios, we have included these calculations. We began with 2sqrt(6)4sqrt(2).
