The slope is 4 (no units), and the ladder is 16.492 feet long. (rounded)
The ladder is 7 foot up the wall if the ladder if the ladder is 3 ft away from wall.
The best tip I've come to is that for every four feet of height you have to climb, move the base one foot away from the wall. Better still is to have someone foot the ladder, or to fasten the ladder with a rope, preferably near the top of the ladder to avoid the ladder sliding sideways.
assuming the wall and ground make a 90 degree angle with one another, Pythagorean's Theorem states the ladder will go 8 feet up the wall.
An inclined plane is any surface with an upward slope away from a horizontal line. A wedge fits this description, however it could also be classified differently as having a declining slope from a parallel horizontal surface.
Using Pythagoras' theorem the length of the base is 7 feet

You lean a ladder that reaches to the top of a house. You want to measure how tall the house is, but you can't measure it. The base of the ladder is 6 feet away from the house and the ladder is 26 feet long. How tall is the house?
The ladder is 7 foot up the wall if the ladder if the ladder is 3 ft away from wall.
This should've been done as the foundation of the house was being built. The ground needs to slope away from your house so that it provides as a water runoff away from your house. From a level base, a 10 to 20 degree slope is what you need to have the ground slope away from your house. This slope should be at a minimum distance of 1 meter to a max of 3 meters. The countour of the rest of your lawn shouldn't matter past this point.
Slope dirt downward and away from foundation, extend downspouts and keep gutters clean, and in severe cases, install drainage ditches.
Take the slab out and pour a new one with the right slope. Rent a concrete saw and cut a few grooves in it making the groove deeper away from the house. This will let the water drain off of the slap and away from the house. If the slab is separate from the house, you might be able to mud jack it at the house and raise it enough to slop it away from the house. Mud jacking is not terribly expensive.
I usually like 12" from dirt to the 1st wood Code requires AT the building a min of 6" If you will be adding mulch then you need to allow more clearance The ground must then slope away from the house for 10' The slope must be around a 5% slope
A thermostat for heating or a thermometer for air temperature is typically placed on an inside wall (not outside wall), and away from heating vents or direct sunlight.
because right away you can tell the slope and y-intercept
Using Pythagoras' theorem the length of the ladder is 20.248 feet

No. if the floor is smooth you must have friction between the ladder and the floor, or the ladder would just slide away. Technically you could do without friction between wall and ladder, but even that can be helpful in preventing the ladder from going sideways.
