- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 2
Hypotenuse <em>c</em> = 7
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: x² + 2² = 7²
- Isolate <em>x </em>term: x² = 7² - 2²
- Exponents: x² = 49 - 4
- Subtract: x² = 45
- Isolate <em>x</em>: x = 3√5
- Evaluate: x = 6.7082
- Round: x ≈ 6.7
