If you are asking for the other side of the ramp, it will make a 90 degree angle meaning you will have a right triangle. In Order to find this, we will have to use the Pythagorean theorem. Lets plug in our values. Since the ramp is slanted, it will be your hypotenuse.
2^2+b^2=8^2
Lets go ahead and square our values
4+b^2=64
We will want to subtract 4 from bot sides to get your B value alone.
b^2=60
Now since B is squared, we will have to take the opposite of squaring a number. We will need to take the square root o 60.
Your B value will be
b= 7.75 (Rounded)
b=7.74596669241 (Not rounded)
I hope this is what you are asking help on xx.
