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.
How big should ladder be to reach roof of house?
To determine the appropriate ladder length to reach the roof of a house, you should consider the height of the roof and the angle at which the ladder will be placed. A general rule is to use a ladder that is at least 3 feet taller than the height you need to reach. For example, if the roof is 20 feet high, a ladder of at least 23 feet would be ideal to ensure safety and stability. Always ensure the ladder is positioned at a safe angle, typically around 75 degrees.
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?
A rope ladder rung on a ship is typically called a "stave" or a "rung." It serves as a step for climbing up or down the ladder.
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 is the very top of a ladder called?
The very top of a ladder is called the "top rung." It is the highest step on the ladder and marks the end of the climbing surface.
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
