Explanation:
We view the ramp as a right triangle. The hypotenuse is 4.2 and the vertical side .7, which is opposite the angle 
θ
 we seek.

I'm going to finish the problem but I'll note if we were actually building the ramp we don't need to know the angle; this sine is sufficient.

which I think is a pretty steep ramp for a wheelchair.
There will be another inverse sine that is the supplementary angle, around

, but we can rule that out as a value for a ramp wedge angle.

Answer:
The ratios are both identical (3/5 and 3/5).
Step-by-step explanation:
sin x° is equivalent to O/H, or the opposite/hypotenuse sides of the triangle. Therefore:
sin x° = 3/5.
cos y° is equivalent to A/H, or the adjacent/hypotenuse sides of the triangle. 
cos y° = 3/5.

The ratios are identical.
 
        
             
        
        
        
First let's calculate the profit in the deal, subtracting the market value and the selling value:

So the profit is $55,000.
Now, calculating the fee of 10% of the profit, we have:

So the fee is $5,500, therefore the correct option is the fourth one.
