Specifically, this is a restatement of the Pythagorean Theorem:", "> In a right triangle, the square of the hypotenuse (the longest side opposite the right angle) equals the sum of the squares of the other two sides.", "Here,:", "- ( 12 ) and ( x ) are the legs of the triangle
\n- ( 13 ) is the hypotenuse", "---", "## Step-by-Step Solution to Solve for ( x )", "To solve for ( x ), follow these algebraic steps:", "1. Write the full equation:
\n [
\n x^2 + 12^2 = 13^2
\n ]", "2. Calculate the squares of 12 and 13:
\n [
\n x^2 + 144 = 169
\n ]", "3. Isolate ( x^2 ) by subtracting 144 from both sides:
\n [
\n x^2 = 169 - 144 = 25
\n ]", "4. Take the square root of both sides:
\n [
\n x = \sqrt{25} = 5
\n ]", "> ✅ Thus, ( x = 5 )", "This result tells us that when two perpendicular sides of a right triangle measure 5 and 12 units, the hypotenuse is 13 units—a perfect Pythagorean triple: ( (5, 12, 13) ).", "---", "## Why Is ( x^2 + 12^2 = 13^2 ) Important?", "### 1. Real-World Applications
