You can put this solution on YOUR website!
The answer to your question lies on the Pythagorean theorem.\r
\n" ); document.write( "\n" ); document.write( "\"+c%5E2+=+b%5E2+%2B+a%5E2+\"\r
\n" ); document.write( "\n" ); document.write( "But, if you are finding for a, the solution would be:\r
\n" ); document.write( "\n" ); document.write( "\"+%28c%5E2+-+b%5E2%29+=+%28%28b%5E2+%2B+a%5E2%29+-+b%5E2%29+\"\r
\n" ); document.write( "\n" ); document.write( "then...\r
\n" ); document.write( "\n" ); document.write( "\"+c%5E2+-+b%5E2+=+a%5E2+\"\r
\n" ); document.write( "\n" ); document.write( "then...\r
\n" ); document.write( "\n" ); document.write( "\"+sqrt%28+c%5E2+-+b%5E2+%29+=+a+\"\r
\n" ); document.write( "\n" ); document.write( "Use this formula. Here are the step by step version:\r
\n" ); document.write( "\n" ); document.write( "\"+sqrt%28+c%5E2+-+b%5E2+%29+=+a+\"
\n" ); document.write( "\"+sqrt%28+40%5E2+-+9%5E2+%29+=+a+\"
\n" ); document.write( "\"+sqrt%28+1600+-+81+%29+=+a+\"
\n" ); document.write( "\"+sqrt%28+1519+%29+=+a+\"\r
\n" ); document.write( "\n" ); document.write( "Thus, the equation will produce an answer of approximately 39. So that I could be more precise, 38.97435053981015345483629909243.
