I am building a ramp for my shed and need some help.
I to use *2x8 x 4ft* long as stringers and can not get the measurements right
to get the angles for the ground cut and the ledger cut.
The height from the ground to the floor is *10 inches*

Can some one help with this dilemma

Angle for the ground cut is arcsin(10/48) = 12 degrees
Angle for ledger cut = 90 degrees - (angle for ground cut) = 78 degrees

Is there a calculator on line to derive at the results for those who do
not know trig? I wish I did but do not.

If you just use a framing square you don't need any math at all and it
will be perfect every time no matter what the rise and run ends up
being.
