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
The distance in the vertical direction.

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.
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.
10 feet, and it is at a very dangerous angle.
Height does not affect distance.

The shortest distance from the given information will be its 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.
That is called the amplitude.
Measure human height by the transitive property. Stand up against the wall and make a mark at your height. Then measure the distance from the floor to the mark. You are as tall as the mark is above the floor.
Height ... how tall is that basketball player? Distance ... how far can I spit a lugie?
Formula for working out height of a tree is (distance from eye to base of tree/distance from eye to base of stick) x length of stick = tree height.(distance from eye to base of tree/distance from eye to base of stick) x length of stick = tree height is the formula for working out height of a tree.
