Solution
Solution Steps
Step 1: Apply the Pythagorean theorem
The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, both legs have a length of 6, and we are looking for the length of the hypotenuse, c. So, the equation becomes:
c² = 6² + 6²
Step 2: Simplify the equation
c² = 36 + 36
c² = 72
Step 3: Solve for c
Take the square root of both sides of the equation to solve for c:
c = √72
Step 4: Simplify the radical
√72 can be simplified as follows:
√72 = √(36 * 2) = √36 * √2 = 6√2
Step 5: Approximate the value
The exact answer is 6√2. To approximate this value, we can use a calculator to find the square root of 2 and multiply it by 6:
6 * √2 ≈ 6 * 1.414 = 8.485
Rounding to the nearest thousandth gives 8.485.
Final Answer
The exact length of the side is $6\sqrt{2}$.
An approximation of the side is 8.485.
