Pythagorean Theorem:
\n" ); document.write( " $\"a%5E2%2Bb%5E2=c%5E2\"$ a and b are legs, c is the hypotenuse. This formula is used anytime you are given a right triangle with one missing side length.
\n" ); document.write( " $\"12%5E2%2Bb%5E2=15%5E2\"$ Simplify
\n" ); document.write( " $\"144%2Bb%5E2=225\"$ Subtract 144 from both sides.
\n" ); document.write( " $\"b%5E2=81\"$ take the square root of both sides.
\n" ); document.write( " $\"b=9\"$ \n" ); document.write( "
