The ratio of the height to the base of a skateboard kicker ramp must be 4:1 chose all that apply

We are given various skateboard kicker ramp with different height and base
For the first triangle,
The heigth = 3 ft
Base = 12 ft
The ratio of height to base = 3/12
= 1 : 4..
Second figure,
The height = 1 ft
Base = 1.5 ft
[tex]\begin{gathered} \text{Ratio of height to base = }\frac{6}{1.5} \\ 1.5\text{ = }\frac{3}{2} \\ \text{Ratio = }\frac{6}{\frac{3}{2}} \\ \text{Ratio = }\frac{6\text{ x 2}}{3} \\ \text{Ratio = }\frac{12}{3} \\ \text{Ratio = }4\text{ : 1} \end{gathered}[/tex]Only the first figure and the second figure will give you 4 : 1 as the ratio of hei
