Find the missing side length

10 ft and 18ft

To find the missing side length of a right triangle, we can use the Pythagorean theorem.

In a right triangle, the squares of the two shorter sides (legs) will equal the square of the longer side (hypotenuse).

Let's denote the missing side length as x.

Using the Pythagorean theorem:
x^2 = 18^2 - 10^2
x^2 = 324 - 100
x^2 = 224
x = √224
x ≈ 14.97 ft

Therefore, the missing side length is approximately 14.97 ft.
