Answer:
B. 112°
Step-by-step explanation:
4x -4 = (3x+4) + (2x-44)
4x -4 = 5x - 40
5x - 4x = -4 + 40
x = 36
∠BCA = 3 * 36 + 4 = 112
Let's say x is longest side, y is shortest side and z is the other side. So we have some equations such that

(by the first sentence)

(by the second sentence)

(by the third sentence)
By the second equation, we have

and if we use it in the first equation, then

. So

Since

, if we use it in the third equation the we have

then

Therefore
