can someone pls solve this I'm really struggling with geometry and have no clue what to do

Answer:
B 112
Step-by-step explanation:
Supplements equal 180 degrees
J+K = 180
8x+ 4x+12 = 180
Combine like terms
12x +12 = 180
Subtract 12 from each side
12x+12-12=180-12
12x = 168
Divide each side by 12
12x/12 =168/12
x=14
We want to find angle J
J= 8x
J = 8(14)
J = 112
