If a 25 foot ladder is leaning against a housemand it has a base of 9 feet from the house. The ladder is moved 6 more feet from the house how far will the ladder slide down the house?

By Pythagoras, if the initial height of the ladder is H1 feet, then
252 = H12 + 92 so H12 = 252 - 92 = 544 so that H1 = 23.32 ft.
After the move, the base of the ladder is 15 ft from the wall. If the height now is H2 feet, then
252 = H22 + 152 so H22 = 252 - 152 = 400 so that H2 = 20 ft.
So the ladder will slide down 3.32 ft or 3 ft 3.9 inches, approx.

What is an example of geometry in real life?
A roof on a house is a obtuse angle or triangle. A stop sign is a octagon. A window is a quadrilateral. A kite is a rhombus. A ladder leaning against a building is a right angle. And bars in gymnastics are parallel lines. Last editing by: A.M.B.

How high is a wall if the ladder is 18 ft high and 14 ft from the house?
The bottom of the ladder is 14 feet from the house and the ladder is an 18 foot ladder that reaches to the top of the house. The question is how tall is the wall of the house? I reworded it to show some assumptions I made about what you are asking.If these are not true, let me knowSo the ladder, the wall of the house and the distance from the ground to the house form a right triangle with hypotenuse 18 and base 14.Now, 142 +x2 =182where x is the height of the wall.Solving for x we find x=(Square root (324-196)=Square root 228since 228 is 4x57 the answer is2(square root (57)57 is 3 x19 so it won't help to simplify it more.
What is a no roll in craps?
A no roll is when one or both of the dice lands somewhere other than on the table, like on top of the house bankroll. It can also be called a no roll when the shooter doesn't throw the dice properly, or very rarely, when one die stops in a position where is it leaning up against something and it can't be determined what the topmost number is.

A painter is standing at the base of a ladder that is leaning against the side of a house What angle do the ladder and the house form?
It can be any angle that is more than zero degrees and less than 90 degrees. <><><> It will be an ACUTE angle, and if the ladder is placed properly (1 ft out for each 4 ft up) the angle between wall and ladder will be ABOUT 18 degrees.

A 30 foot ladder leaning against the side of a house makes a 70 degrees 5' angle with the ground how far up the side of the house does the ladder reach?
Round the base angle to 70 degrees and use the sine ratio: 30*sine 70 degrees = 28.19077862 feet Height of ladder from the ground = 28 feet to 2 s.f.

A 15feet ladder leaning against a bulding touches the wall 12 feet above the ground. How far from the building is the bottom of the ladder?
This is a standard right triangle problem. The formula for solving the parameter of a triangle is a^2 + b^2 = c^2 Also known as the Pythagorean theorem. So, in this problem, the ladder is the hypotenuse, that is to say side c of the triangle. The height of the house is 12 or b in this example. Finally, the distance from the house, is the unknown distance a . Applying this knowledge gives us a^2 + 12^2 = 15^2 Simplified to a^2 + 144 = 225 225 - 144 = 81 So now you have a^2 = 81. Taking the square root of each side of the equation, we're left with: a = 9 So, the ladder is nine feet away from the house at the bottom of the ladder.
What is the height of a latter if its leaning on a 10 meter house and its 3 meters away from the house?
Pythagorean theorem : root(10^2+3^2)=root(109) Somewhere between 5 metres and 12 metres. Did you want to know how long the ladder is?
