Answer:
b=84
Step-by-step explanation:
from your equation, subtract 3969 from each side
you are left with b^2=7056
sqrt b^2 = sqrt 7056
b=84

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:
A. Equation is 
B. Cost is $88
Step-by-step explanation:
A)
Suppose you rent for x hours and each hour costs $15.75
<u><em>How much would you need to pay?</em></u>

Moreover, there is a $25 dollar (fixed) deposit for renting, so that gets added to your payment. All in all, you have to pay 
This is the equation of renting a snowboard for x hours.
Equation is 
- Where x is the number of hours you rent the snowboard, and
- c is the total cost
B)
If you are renting from 8.30 to 12.30, you are basically renting for 4 hours.
To know how much it will cost, you simply plug in 4 into x (in the equation):

Cost is $88
