[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

Leg <em>a</em> = 35

Leg <em>b</em> = 12

Hypotenuse <em>c</em>

<em />

<u>Step 2: Solve for </u><em><u>c</u></em>

  1. Substitute in variables [Pythagorean Theorem]:                                          35² + 12² = c²
  2. [Hypotenuse] Rewrite:                                                                                   c² = 12² + 35²
  3. [Hypotenuse] Evaluate exponents:                                                                c² = 144 + 1225
  4. [Hypotenuse] Add:                                                                                          c² = 1369
  5. [Hypotenuse] [Equality Property] Square root both sides:                           c = 37
