Answer:
-63
Step-by-step explanation:
1)inside the triangule is 180º .There are 3 angules, one with 120º, theta and
angle ACB, lets call it x.
x + theta + 120 = 180
x + theta= 180-120
x + theta= 60
x= 60- theta
angle ACB= 60- theta
n+29 is that what you mean
The final result is: C) x(x - 8)(x + 8).
