To calculate the value of x, you can apply:
Tan(α)=Opposite leg/Adjacent leg
In this case, the opposite leg is "x", and the adjacent leg is 15. The angle α is 30° (α=30°)
When we substitute this values, we obtain:
Tan(α)=Opposite leg/Adjacent leg
Tan(30°)=x/15
x=(15)(Tan(30°))
x=5√3

Step-by-step explanation:
<u>Parabola in Vertex Form</u>
To express the equation of a parabola in vertex form we must complete squares. The equation is given as
![5x^2 + 30x + 15 = 0](https://tex.z-dn.net/?f=5x%5E2%20%2B%2030x%20%2B%2015%20%3D%200)
The first step is to factor 5 and leave space to complete the third term in the parentheses, along with a space outside it to compensate. This should look like
![5(x^2 + 6x\text{........)} + 15....... = 0](https://tex.z-dn.net/?f=5%28x%5E2%20%2B%206x%5Ctext%7B........%29%7D%20%2B%2015.......%20%3D%200)
Those spaces need to be filled out like shown in the step 2. Thus the correct option is D
