We can solve this problem using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

In this case, the diving board acts as one side of the right triangle, the ladder acts as the hypotenuse, and the distance between the base of the diving board and the ladder acts as the other side of the right triangle.

Let's call the height of the ladder h. The distance between the base of the diving board and the ladder is given as 5 feet.

Using the Pythagorean theorem, we have:

h^2 = 10^2 + 5^2
h^2 = 100 + 25
h^2 = 125

Taking the square root of both sides, we find:

h ≈ √125
h ≈ 11.18

So, approximately, the ladder is 11 feet tall.
