How far is the base of a ladder that is 25 feet long leaning on a building 24 feet above the ground?
Using Pythagoras' theorem the length of the base is 7 feet
How far should a ladder extend above the roof?
1 metres
What is the elevation of your house?
It can mean the height from the ground to the roof peak, or the ground elevation above or below sea level.
How do you measure the height of a round above the ground pool for a beaded liner?
Pie times the radius squared
What is the height from floor to window sill?
It depends on how heigh the window sill is from the ground. it can be right above it, or far from the floor.
A 15-foot ladder is leaning against a 30-foot wall The bottom end of the ladder is 9 feet from the wall How many feet above the ground does the ladder touch the wall?
12
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 15 foot ladder is leaning against a 30 foot wall The bottom end of the ladder is 9 feet from the wall How many feet above the ground does the ladder touch the wall?
12 feet. It is actually pretty easy, if you remember that a 3x4x5 triangle is always a right angle. divide by 3 and you have the 3 and 5 all you need is the four multiplied by 3.
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.
Two ladders of lengths 8m and 10m are leaning two walls. three point of intersection is 3m above the ground What is the distance between the walls?
For the ladder with the length of 8m 8.37m from the wall For the ladder with the length of 10m 10.44m from the wall
How far is the base of a ladder that is 25 feet long leaning on a building 24 feet above the ground?
Using Pythagoras' theorem the length of the base is 7 feet
Can you move a ladder on a Gibraltar pool?
If it is an above ground yes
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.
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.
A woman has a ladder that is 13 feet long. if she sets the base of the ladder on level ground 5 feet from the side of the househow many feet above the ground will the ladderbewhenitrestsonthehouse?
12 feet
What is the formula for a 15 foot ladder is leaning against a 30foot wall the bottom end of the ladder is 9 feet from the wall how many feet above the ground does the ladder touch the wall?
If you take the trouble to draw a sketch of the situation that you've described, the method of solution, as well as the answer, will jump out at you. The ground, the wall, and the ladder, form a right triangle. The base is 9-ft, and the hypotenuse is 15-ft. If you've been assigned this problem as homework, then you've sat through enough geometry in class to know how to work with the right triangle. The length of the missing side is 12-ft, and it makes no difference how high the wall is, as long as it's high enough to support the upper end of the ladder.
