[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse
Step-by-step explanation:
<u>Step 1: Identify</u>
a = 68
b = 51
<u>Step 2: Solve for </u><em><u>c</u></em>
- Substitute [PT]: 68² + 51² = c²
- Exponents: 4624 + 2601 = c²
- Add: 7225 = c²
- Isolate <em>c</em>: 85 = c
- Rewrite: c = 85
