Answer:
A. 4.8°
Step-by-step explanation:
We have that,
The horizontal distance for the ramp = 12 feet.
Maximum height of the ramp = 1 feet.
So, we get that the value of the angle 'x' made by the ramp with the ground is given by,

i.e. 
i.e. 
i.e. 
i.e. x = 4.8°
Thus, the maximum angle made by the ramp with the ground is 4.8°.
They are a subset to squares
Add the equations in order to solve for the first variable. PLug this value into the other equations in order to solve for the remaining variables.
The answer is:
(2, -3)
I think u have to Multiply the 100 and 0.30 and that would be 30
