What we have here is a bisected angle. What this means is that an angle is being cut in half to create multiple angles. In this case angle E has been bisected. Since that is the case, angles 1 and 2 are equivalent to each other. Now that we know this we can solve for x.

Equation:

x + 8 = 2x - 1

8 = x - 1

9 = x

The safety inspector notes that Ray also needs to plan for a vertical ladder through the center of the coaster's parabolic shape

wariber [46]

f(x) = 3(x^2 + 3x) + 12 = 3(x+1.5)^2 +5.25

So you can see the vertex is at (0,5.25) when x = -1.5
<span>The axis of symmetry then lies in x = -1.5</span>
