A 15 foot ladder is leaning against a 30 foot wallthe bottom end of the ladder is 9 feet from the wallhow many feet above the ground does the ladder touch the wall?
12 feet.
If a 15foot ladder is leaning against a 30foot wallthe bottom of the ladder is 9feet from the wallhow many feet above the ground does the ladder touch the wall?
Use Pythagoras' theorem: 152-92 = 144 and the square root of 144 is 12 Answer: 12 feet
A 40 foot ladder is placed against a building the ladder forms a 75 degree angle with the ground How high up the building does the ladder reach?
115
A 13 foot ladder is leaning against a wall. If the point where the ladder meets the wall is 12 feet above the ground how far from the base of the wall is the the ladder?
To find the distance from the base of the wall to the bottom of the ladder, we can use the Pythagorean theorem. The ladder, wall, and ground form a right triangle, with the ladder as the hypotenuse. Given that the ladder is 13 feet and the height of the wall is 12 feet, we can calculate the base distance (x) using the equation (x^2 + 12^2 = 13^2). Solving gives (x^2 + 144 = 169), leading to (x^2 = 25), and thus (x = 5) feet.
What would you use to measure a ladder?
To measure a ladder, you can use a tape measure or a ruler for precise measurements of its height, width, and depth. It's important to measure from the base to the top rung to ensure accuracy. Additionally, if you want to assess the ladder's angle when set up, a protractor or an inclinometer can be useful.

How important is a ladder in a swimming pool?
Ladder's are very important in a swimming pool. If you don't have a ladder, people can get hurt. If there is an emergency and someone needs help, it would take a while for the person to get help.

If A ladder leaning against a wall makes a 60 angle with the ground the base of the ladder is 3 m from the building how high above the ground is the top of the ladder?
This answer uses trigonometry to avoid a lot of work:tangent = opposite/adjacent and tangent*adjacent (base of ladder from the building) = opposite (height of ladder above ground)So: tangent 60 degrees*3 = 5.196152423Therefore: Top of the ladder above ground = 5.2 meters correct to one decimal place.More laborious methodThe right triangle formed by the wall, ground and ladder has sides in the ratio of 1::2::sq-rt-of-3. The shortest side is the one opposite the 30 degree angle, i.e., the given distance from wall to base of the ladder--3 m.The length of the ladder represents the hypotenuse of the triangle, and is twice as long, hence 6 m.And the height of the ladder's top from the ground is proportional to the third side whose length is sq-rt-3 times that of the shortest side. Sq-rt-3 is about 1.732, so height of the ladder's top at the wall is about 5.20 m, or 520 cm.

12 feet.
A ladder that leans against a building makes an angle of 49 degree with the ground and reaches a point on the building 12m above the ground Find the length of the ladder to the nearest meter?
The ladder forms a right angle with the building: the ground and the building forming the right angle and the ladder forming the hypotenuse. If the length of the ladder is L metres, then sin(49) = 12/L So L = 12/sin(49) = 15.9 = 16 metres.
Are in-ground or above-ground pools better?
Above ground pools are cheaper to install. They offer an easy safety feature which is taking the ladder away while the pool is not in use. In ground pools offer a deeper pool that you can do laps and exercise more freely.
What is the minimum height of a ladder required for me to reach the top of the roof?
To determine the minimum height of a ladder needed to reach the top of the roof, measure the vertical distance from the ground to the top of the roof. This measurement will be the minimum height required for the ladder.
Can a roofer who wants to repair your roof that is 28 foot above the ground level use a 28 feet 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.
