10 To find the length of BC, we can use the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse).

In this case, AC is the hypotenuse, and AB and BC are the two shorter sides.

Let's label the length of BC as x.

According to the Pythagorean Theorem, we have the equation:

AB^2 + BC^2 = AC^2

Substituting the given values:

40^2 + x^2 = 50^2

Simplifying:

1600 + x^2 = 2500

Next, we can subtract 1600 from both sides:

x^2 = 2500 - 1600

x^2 = 900

Finally, we can take the square root of both sides to solve for x:

x = √900 = 30

Therefore, the length of BC is 30 feet.
