A ladder of length 5m rests against a wall The foot of the ladder is 1.7m from the base of the wall How far up the wall does the ladder reach?
6.7
A ladder is resting against a wall The top of the ladder touches the wall at a height of 6 feet Find the length of the ladder if the length is 2 feet more than its distance from the wall?
10 feet, and it is at a very dangerous angle.
A ladder is leaning against a building The base of the ladder is 5 feet from the building The building is perpendicular to the ground and the top of the ladder reaches 10 feet high on the building?
15
The distance from the bottom of the ladder to the building is18 foot less than the length of the ladderHow high up the building is the top of the ladder if that distance is 1 ft less than the length?
X is the length of the ladder and the hypotenuse of a Pythagorean Triangle so: x2 = (x - 18)2 + (x - 1)2 ie x2 - 36x + 324 + x2 - 2x + 1 which is 2x2 - 38x + 325 this is the same as x2 - 38x + 325 = 0 which factorises as (x - 13)(x - 25) so the ladder is either 13 or 25 feet long but it can't be 13 so the lengths are 25ft ladder, 7 feet from the building and 24 feet up the wall.
An extension ladder's distance from the base of a building should be what proportion of it's total extension?
It is not a proportion. There needs to be aroubd a 75 degree angle from the ground to the base. If it is too flat the ladder can slip out from underneath you. If it is too steep you can tip back. There is usually an angle at the bottom of the ladder if that is flat on the ground then that should be the safest angle (75 degrees)
What is 4 to 1 ratio for ladder use?
That probably refers to the ratio between the length of the ladder, and the distance at which you place the bottom part of the ladder from the wall. If this distance is too short, you have the risk of the ladder falling backwards.
A ladder is leaning against a building so that the distance from the ground to the top of the ladder is one foot less than the length of the ladder. Find the length of the ladder if the distance from the bottom of the ladder to the building is 5 feet?
A. 11 feet B. 13 C. 12 D. 14.
How wide is a ladder?
OSHA is unclear but the distance should be 12". The first step on a ladder can vary between 6" and 18".
A ladder is leaning against a building the distance from the building to the botton of the ladder is 7 feet the ladder is 25 feet long how high up the building is the top of the ladder?
It is: 24 feet by using Pythagoras' theorem
What is the Cosmic distance ladder?
The cosmic distance ladder is a series of methods that astronomers use to measure distances to objects in space, such as stars, galaxies, and other celestial bodies. It relies on combining various distance measurement techniques, such as parallax, standard candles, and redshift, to determine distances at different scales in the universe. This ladder helps us understand the vastness and structure of the cosmos.
Can a roofer who wants to repair your roof that is 28 feet above the ground level use a 28 foot ladder?
No. since the ladder must be on an angle it must have room so that the length of the ladder is equal to the 282 + (distance between bottom of ladder and house)2.

6.7
A ladder 15ft long leans against a wall the top of the ladder reaches a height that is 3 ft more than twice the distance from the base of the ladder to the wallhow high up the does this ladder reach?
18
What should be the horizontal distance in feet for a ladder to the 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.

10 feet, and it is at a very dangerous angle.
What type of simple machine is a step ladder?
A step ladder is a type of inclined plane simple machine. It allows you to raise yourself to a higher position by exerting a smaller force over a longer distance along the length of the ladder.
