Approximately 13.27 ft
Using pythagorean theorm:
a²+b²=c² (c being the length of the hypotenuse)
20²+b²=24²
400+b²=576
b²=176
b= root of 176
b= approx. 13.27
It can be any angle that is more than zero degrees and less than 90 degrees. <><><> It will be an ACUTE angle, and if the ladder is placed properly (1 ft out for each 4 ft up) the angle between wall and ladder will be ABOUT 18 degrees.

It is: 25*cosine(65) = 10.565 feet rounded
Answer your self dont know
You lean a ladder that reaches to the top of a house. You want to measure how tall the house is, but you can't measure it. The base of the ladder is 6 feet away from the house and the ladder is 26 feet long. How tall is the house?
Using Pythagoras' theorem it is 9 feet
It should be placed 2 ft from the wall

Well, using a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse, you need to square 39 and 36. Then your equation should look like a^2 +1296 = 1521, then solve for a^2, getting the variable by itself, so you have a^2 = 225. Then take the square root of both sides leaving you with a= 15. So, the ladder must be placed 15 feet from the base of the house.
15 meters, or less, depending on the angle.
