Answer:
70°
Step-by-step explanation:
it's an acute angle so it couldn't be 110 since that would make it obtuse.
It would be 330 if rounded to the nearest 10th place
The function in vertex form is

(refer to your other post I solved it there).
The general form of quadratic equations in vertex form is

, where (h, k) is the vertex of the parabola.
Here, a = 1, h = -6 and k = -54
Therefore, the vertex is (-6, -54) and it is a maximum because a = 1 is postive.
