Step-by-step explanation:
Diagram of given scenario is shown below.
Given that,
Horizontal Distance of Skateboard ramp is
ft.
Height of Skateboard ramp is
ft.
From figure,
It is forming a Right angle triangle
.
In
,
and
.
Clearly see that we need to find measure of angle
.
Using Trigonometric ratio:

So, 
Then 
Therefore, Angle made by ramp with ground is ≈
