The foot of a ladder is placed 5 feet from a building the top of the ladder rests 12 feet up on the building how long is the ladder?
13 feet
Ken leans a 12-foot ladder against his house He places the ladder so that the base is 5 feet from the house How far up the house does the ladder reach?
10.9 [11]
How long must a ladder be to reach the top of a 20 foot wall if the ladder and the wall form a 32 degree angle?
Hypotenuse = 20/sin580 = 23.58356807 Length of ladder: rounded to 23.584 feet
A ladder rests against a wall the top of the ladder reaches 15 feet up the wall and makes an angle of 53 with the wall how long is the ladder?
If the wall is straight and the ground level then this is an outline of a right angle-triangle. If the top of the ladder makes an angle of 530 with the wall then the bottom of the ladder must make 370 to the ground. Use the sine ratio to find the length of the ladder (which will be the hypotenuse) sin = opp/hyp rearranged to hyp = opp/sin hyp = 15/sin370 = 24.92460212 feet So the length of the ladder is 25 feet correct to the nearest foot.
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.
Do skew lines intersect?
SKEW LINES are neither parallel nor intersecting.
Horizontal lines on a map of the earth is called?
Latitude. It may be helpful to think of a ladder when trying to remember this, as Ladder sounds similar to latitude, and ladders have many horizontal bars.
How do you remember latitude lines run from east to west?
If you remember that the rungs of a ladder are like the latitude lines on that ladder. That's how I remember it.

What the step of ladder is called?
The steps on a ladder are called rungs (rung, singular)
What is a rope ladder rung on a ship called?
I've seen them called Jacob's Ladders.
Are the rungs on a stepladder parallel intersecting or skew?
No; the rungs of a ladder and the sides of a ladder intersect. Skew lines do not intersect.
What are the step of a ladder call?
The steps of a ladder are called rungs.
Name a real world example of parallel lines?
-- a railroad track -- the sides of a ladder -- the rungs (steps) of a ladder -- the two curbs on the street
What is easy way to remember latitude runs across the map?
Longitude lines go up and downLatitude lines go round and roundOr remember LADDER (Lati) -tude lines are like the rungs of a ladder that you can climb; LONG-itude lines run long-wise from North to South
