Answer:
The only one
Step-by-step explanation:
The one that is shown has a negative b^2-4ac value.
We know this because the function has no real roots -> that means that they must be complex, which can only occur if b^2-4ac < 0
The answer is 45 because supplement means the sum of 180 so 180 divided by 4 is 45 and t=45
