Answer:
The answer is B because it's correct you guessed it right
Step-by-step explanation:
I think I know what you're asking but I'm not 100% but there would be no equal sides or equal angles. Hope this helps!
If f(x) is = to 0 then that means that you would have to plug the 0 in for all of the x that are in the function and the solve it.
f(x)= x3-4x-1
f(0)= (0)3-4(0)-1
0 0 0 -1
-1
so that means that -1 would be the answer for the function
I think it could be 40° or 130°. Im not 100% sure however because i dont know how much all the numbers add up to. It could either be 180° or 270°
