Answer:

C.) 5.1

Explanation:

First, solve for J's angle of degrees

180 - (120 + 40) = 20

Second, fill in all the information that you know in the equation

sin(20) / 2 and sin(120) / k

Third, cross multiply

k x sin(20) = 2 x sin(120)

Fourth, solve for k

k x sin(20) / sin(20) = [2 x sin(120)] / sin(20)

k = [2 x sin(120)] / sin(20)

k = 5.0641777.....

Fifth, round to the nearest tenth

k = 5.1
