Hello Delvin!
This problem can be represented by a right triangle. Since the ladder of the slide is vertical, we can assume it forms a right angle with the ground. The length of the slide is the hypotenuse of the triangle because it is the side opposite the right angle, and the distance between the end of the slide and the ladder is the third side.
Remember that the Pythagorean theorem states for any right triangle, a2 + b2 = c2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides. In this problem, the hypotenuse is 17, and we know the length of one other side, which is 8.
c = 17
a = 8
We can plug these numbers in to the Pythagorean theorem and solve for b.
82 + b2 = 172
64 + b2 = 289 Here I squared 8 and 17
b2 = 225 Here I subtracted 64 from both sides
b = ±15
Since b is a side length it cannot be negative, so b = 15.
The distance between the bottom of the ladder and the foot of the slide is 15 feet.
Good luck with your homework!
