If you draw a picture you will see that you have a right triangle with the ladder's length as the hypotenuse. Since we are trying to find the length, we label it as L.
The height 12 is given and the distance from the wall is L-3.
By the Pythagorean theorem:
(L-3)2 + 122 = L2
L2-6L +9 +144 = L2
L2-6L + 153 = L2
-6L + 153 = 0
153 = 6L
L = 153/6 = 25.5 ft

What does height equal?
The distance in the vertical direction.
Can you finish this analogy clock is to time as ruler is to .?
Clock is to time as ruler is to distance.
A ladder 15ft long leans against a wall the top of the ladder reaches a height that is 3 ft more than twice the distance from the base of the ladder to the wallhow high up the does this ladder reach?
18
What is the maximum and minimum possible difference between two boys who observe the angle of elevation of a 50m tall tower to be 30 and 45 degrees?
The max. distance between the two boys will be 36.6 ft. if they are lying with their faces on the ground. The min. distance between them depends on how tall they are (height of eye). Say height of eye is 5 ft. then the distance between them will be 32.94 ft.
When you use a formula to calculate the area of a triangle does it matter which base - height pair you use.?
The side you use as the base does not matter. What does matter is that the height is the perpendicular distance between this side and the other vertex. If there is a right angle in the triangle, then use the two sides next to it as the base and height. Otherwise a bit of trigonometry will be required to work out the height of the triangle if it is not given.
A ladder is resting against a wall The top of the ladder touches the wall at a height of 6 feet Find the length of the ladder if the length is 2 feet more than its distance from the wall?
10 feet, and it is at a very dangerous angle.
What is the proper name for the height of a wave?
The proper name for the height of a wave is its amplitude. It refers to the distance from the midpoint (resting position) of the wave to the peak (crest) or trough (lowest point).
What is the height of a wave called it start with an a?
The height of a wave is called its amplitude. Amplitude is the distance from the midpoint of a wave to its crest or trough. It represents the maximum displacement of the wave from its resting position.
What is the distance between a waves crest and its trough called?
The distance between a wave's crest and its trough is called the amplitude. It represents the maximum displacement of the wave from its resting position.
Which characteristic of a wave describe the greatest distance a wave vibratetes from a ressting position?
The amplitude of a wave describes the greatest distance a wave vibrates from its resting position. It is the measure of the height or intensity of the wave.
Vertical distance between a waves crest and trough?
The vertical distance between a wave's crest and trough is called the amplitude. It represents the maximum displacement of a wave from its resting position. The amplitude is a measure of the wave's intensity or strength.
What is used to describe the height of a wave?
The height of a wave is typically described by the wave's amplitude, which is the distance from the midpoint (resting position) of the wave to its peak. Amplitude is a measure of the wave's intensity or strength, and it is often used in physics and oceanography to quantify the size of waves.
How do you measure human height with tape measure?
To measure human height with a tape measure, have the person stand upright against a wall with their heels touching the wall. Place the tape measure flat against the wall, making sure it is level, and mark the height at the top of the person's head. Then, measure the distance from the floor to the mark to determine their height.
A ladder is resting against a wall the top of the ladder touches the wall at a height of 18 feet find the length of the ladder if the length is 6 feet more than its distance from th wall?
24
What is the distance between from crest to trough in a wave called?
If you mean the distance along the direction of propagation, that's a half-wavelength. If you mean the distance perpendicular to propagation (i.e. the "height" of the wave), it's the amplitude.
Was the difference between height and slant height?
Lean a ladder against a wall. Not too steep . . . Give it a nice angle, for safe climbing. The height is the distance between the ground and the place where it hits the wall. The slant height is the length of the ladder.
What is The shortest distance from the base of a parallelogram to its opposite side is?
The shortest distance from the given information will be its height
