Question

A board is leaning against a shed. The distance from the bottom of the board to the shed is 3 feet, and the board touches the shed 4 feet from the ground. How long is the board?

Answer 1

x = 5 feet

Explanation:

To find the length of the board, you can use the Pythagorean theorem

x^2 = 3^2 + (4)^2

Expanding the right side of the equation, we have:

x^2 = 9 + 16

So, x^2 = 25

Taking the square root of both sides of the equation, we have:

x = 5

Therefore, the board is 5 feet long.
