Find the missing side of a right triangle in which a = 12, c = 20, b = ?
\n" ); document.write( "Assuming that side c is the hypotenuse, then you can use the Pythagorean theorem to find side b:
\n" ); document.write( " $\"c%5E2+=+a%5E2%2Bb%5E2\"$ Substitute a = 12 and c = 20.
\n" ); document.write( " $\"20%5E2+=+12%5E2%2Bb%5E2\"$ Simplify.
\n" ); document.write( " $\"400+=+144%2Bb%5E2\"$ Subtract 144 from both sides of the equation.
\n" ); document.write( " $\"256+=+b%5E2\"$ Take the square root of both sides.
\n" ); document.write( " $\"highlight%28b+=+16%29\"$ \n" ); document.write( "
