x^2=(x-4)^2+y^2 height up the wall = y = (x^2-(x-4)^2)^1/2 so if the length of the ladder is 10 feet Y= (100-36)^1/2 = 8
5 meters
Its pythagoras: 102 - 52 = vertical height2. So 100-25 = vertical height2. Then the square root of 75 must = vertical height. Which makes the top of the ladder 8.66 feet (8ft 8 inches) from the ground.
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.

Perimeter didn't 'come from' anywhere. The concept of 'how long is the bottom of the outside of this thing' has always existed. Perimeter is just the name for 'how long is the bottom of the outside of this thing'. As an example, the perimeter of any one of the pyramids has always been the same.About 1600, the English word 'perimeter' was first used to describe 'the distance around the outside of stuff'But, that distance was the same long before that!

This is when a building is separated from the ground that it is built on by large plates. One plate is secured to the ground and the other is secured to the bottom of the building. These plates move a certain distance when the ground shakes.
