Problem
Julie is building a skateboarding ramp by propping the end of a piece of wood on a cinder block. If the ramp begins 76 centimeters from the block and the block is 57 centimeters tall, how long is the piece of wood? centimeters
Solution
Step 1 ：Form a right triangle with height 57 cm, base 76 cm, and the wood piece as hypotenuse.
Step 2 ：Use the Pythagorean theorem: \(hypotenuse^2 = base^2 + height^2\).
Step 3 ：\(hypotenuse = \sqrt{76^2 + 57^2} \)
