Use pythagorean theorem to solve:
(distance from the wall)2 + (height up the wall)2 = (length of the ladder)2
(height up the wall) = sqrt[ (length of the ladder)2 - (distance from the wall)2 ]
Height = sqrt[ (5)2 - (1.7)2 ]

A ladder long rests against a vertical wall If the top of the ladder slides down at a rate of how fast is the bottom of the ladder sliding away when the bottom of the ladder is away from the wall?
If h is vertical height, b=horizontal distance from wall to bottom of ladder and l=lenght of ladder,we can say lsquared = hsquared + b squared. Now differentiate w.r.t. time t. 2l*dl/dt= 2h* dh/dt + 2b*db/dt =0 However this solution doesn't give exactly the same answer when one solves the problem geometrically or using simple pythagorus. For example ,if l=20m and b=12 m and h=16m and db/dt is 2m/s, I calculate dh/dt as !.5 m/s using calculus but 1.717 m/s using geometry or straight Pythagorus. Where is the fallasy inthe method using calculus? Ray Bevan
What is the formula in getting the height of a rectangle?
lenght times height == If it rests on one of the shortest sides , then the altitude is the length of the longer side. If it rest on one of the longer sides, then the altitude is the length of the shortest side. If it is the special case of a square, then any side is an altitude.
Where can you purchase foot rests from?
Foot rests can be bought in a variety of places. One can buy them at furniture stores, home improvement stores, and home supply stores. One may also find foot rests through online retailers.

What is the answer to A 15-m long ladder rests against a wall at an angle of 60 degrees with the ground How far is the foot of the ladder from the wall?
15*cos(60) = 7.5 7.5 m
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.

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
The foot of a ladder is placed 6 feet from a wall If the top of the ladder rests 8 feet up on the wall. how long is the ladder?
62+82=36+64=100 and the squared route of 100 is 10
7.0 m 240 N uniform ladder rests against a smooth wall The coefficient of static friction between the ladder and the ground is 0.65 and the ladder makes a 50.0 angle with the ground How far up?
this is what i have: my question: ladder: weight = 200N = Mg; length = 10m = L firefighter: weight = 600N = mg He goes up ladder x distance. coefficient is 0.5 50 deg angle between ladder and floor what is the max value of x? -------------------- Ff -Fn Ff = Fn 1) Gn = Mg + mg Gn = 200+600=800 2) Ff = mu*Gn Ff = 0.5 * 800 = 400 3) x = (Ff*L*sin50 - Mg(L/2)sin40) / (mg*sin40) [40 deg is 90-50; the 90 is perpendicular to the ladder] x=[(400*10*sin50)-(200*5*sin40)] / [600*sin40] x = 6.28m for more info see: tycho.physics.wisc.edu/courses/phys201/spring08/Lectures/Solids.pdf
What does it mean when a guy rests his head against your head?
It could mean that they really like you.
Silence for berlioz bizet and bartok?
In music by any composer rests indicate the length of silence desired.
If your feet touch the ground and your head rests against the head rests can you sit in the front seat yes or no?
That's kind of subjective it depends on how old you are, your weight, how tall you are and other factors. So yes you can but it's more risky.
