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 
170

, but we can rule that out as a value for a ramp wedge angle.
        
             
        
        
        
Answer:
Step-by-step explanation:
<em>Speed = distance/time</em>
- Distance = 20.4 miles
- Time = 17 minutes = 17*1/60 hours = 17/60 hours
<u>Speed is:</u>
- 20.4 : 17/60 =
- 20.4*60/17 =
- 72 mph
<u>Alyn exceeded the limit by:</u>
 
        
             
        
        
        
2(x+2) = 60
x+2 = 30
x = 28
The correct answer is C
        
                    
             
        
        
        
It will be 20*21 based on the pattern in the chart
