Logan just went down the slide at the playground. He walks 4 feet to get from the end of the slide back to the ladder. Then he climbs 3 feet to the top of the slide again. How long is the slide?
(Pythagorean theorem)
Let's assume the length of the slide is represented by 'x'.
According to the Pythagorean theorem, in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (the hypotenuse).
So, using the Pythagorean theorem:
x^2 = 4^2 + 3^2
x^2 = 16 + 9
x^2 = 25
x = √25
x = 5
Therefore, the length of the slide is 5 feet.
