Answer:
a=10.8; c=4.3
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees.
Two of the angles are given as 40 deg and 120 deg.
Subtract the measures of both from the sum to get the last angle:
180-40-120=20; ∠C=20°
Using Law of Sines: 
8 + 6 + 9 + 12 + 4x / 5 = x Original Problem.
25 + 4x / 5 = x Addition.
25 + 4x = 5x Multiply each side by 5.
25 = x Subtract 4x from each side.
x = 25 Switch equation around.
Answer: x = 25
