Answer:
42
Step-by-step explanation:
First I'm going to assume that C and A are perpendicular.
Because its perpendicular, this creates a 90 degree angle which can be used to create the following equation.
Reduce
11x = 88
x = 8
We then plug in 8 into the equation 6x - 6 in order to solve for that angle.
6(8) - 6

Explanation:
1. The general form of a quadratic in standard form* is ...
An example is ...
The constant c is the y-intercept, so is the easiest bit of information to obtain in this form.
__
2. The general form of a quadratic in vertex form can be written as ...
An example is ...
The ordered pair (h, k) is the vertex of the parabola, so is easy to obtain in this form. Arguably, it may be easier to identify the line of symmetry, x=h, since that requires looking at only one constant, instead of two.
