The formula for the Axis of symmetry is -b/2a. Which is -(-2)/2(1) = 2/2 = 1. The axis of symmetry is the X of the vertex, so just plug the 1 into the equation. So the Y= 0, so the vertex is (1 , 0)

$tan(72)= \frac{y}{x} ; tan(55)= \frac{y}{2.2 + x}$
$y=xtan(72);y=(2.2+x)tan(55)$
So we are to merge the two equations into one, since both of the equations are equal to y. a = b, b = c therefore, a = c.
$xtan(72)=2.2tan(55)+xtan(55)$
We are to isolate x.
$x[tan(72)-tan(55)]=2.2tan(55)$
$x=\frac{2.2tan(55)}{tan(72)-tan(55)}$
The value of x is approximately, 1.9047m
Then, substitute the value of x from $y=xtan(72)$
$y=1.9047tan(72)$
y = 5.862m
Round up, then the answer would be D.
