Use the Pythagorean Theorem to solve
\n" ); document.write( "\"c%5E2=a%5E2%2Bb%5E2%29\"
\n" ); document.write( "Let a=9.75
\n" ); document.write( "Let b=17.24
\n" ); document.write( "Let c=the hypotenuse (the side opposite the right triangle.\r
\n" ); document.write( "\n" ); document.write( ".
\n" ); document.write( "\"c%5E2=a%5E2%2Bb%5E2%29\" [plug-in the values and solve for c]
\n" ); document.write( "\"c%5E2=9.75%5E2%2B17.24%5E2%29\"
\n" ); document.write( "\"c%5E2=95.0625%2B297%29\"
\n" ); document.write( "\"c%5E2=392.2801%29\"
\n" ); document.write( "\"sqrt%28c%5E2%29=sqrt%28392.2801%29\" [take the square root of each side to find the value of \"c\"]
\n" ); document.write( ".
\n" ); document.write( "c=19.806
\n" ); document.write( ".
\n" ); document.write( "check by plugging all of the values back into the original equation:
\n" ); document.write( "\"19.806%5E2=9.75%5E2%2B17.24%5E2%29\"
