A right triangle has leg lengths of 9 units and 12 units. Write an equation that can be
LenKa [72]
<h2>The Pythagorean Theorem</h2>

The Pythagorean Theorem: a^2+b^2=c^2

  • <em>a</em> and <em>b</em> are the two legs in a right triangle
  • <em>c</em> is the hypotenuse (the longest side of a right triangle; opposite the 90° angle
  • <em>*keep in mind that this theorem applies only to right triangles</em>

<h2>Solving the Question</h2>

We're given:

  • Legs = 9 units and 12 units
  • Hypotenuse = <em>c</em>

<em />

Plug these measurements into the Pythagorean theorem:

a^2+b^2=c^2\\9^2+12^2=c^2

⇒ Combine like terms:

81+144=c^2\\c^2=225

<h2>Answer</h2>

c^2=225
