Solution Steps

Step 1: Identify the Right Triangle

The given problem involves a right triangle with sides of lengths 3, 4.5, and 5. We need to find the length of the hypotenuse, denoted as x x .

Step 2: Apply the Pythagorean Theorem

The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse (x x ) is equal to the sum of the squares of the other two sides. The formula is: x2=a2+b2 x^2 = a^2 + b^2 where a a and b b are the lengths of the other two sides.

Step 3: Substitute the Given Values

Substitute the given values into the Pythagorean Theorem: x2=4.52+32 x^2 = 4.5^2 + 3^2

Step 4: Calculate the Squares

Calculate the squares of 4.5 and 3: 4.52=20.25 4.5^2 = 20.25 32=9 3^2 = 9

Step 5: Sum the Squares

Add the squares of the two sides: x2=20.25+9 x^2 = 20.25 + 9 x2=29.25 x^2 = 29.25

Step 6: Solve for x x

Take the square root of both sides to solve for x x : x=29.25 x = \sqrt{29.25} x5.41 x \approx 5.41

Final Answer

The length x x is approximately 5.41.
