\n" ); document.write( "1 yard = 3 feet
\n" ); document.write( "100 yards = 300 feet (multiply both sides by 3)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We have a right triangle with side lengths a = 300 ft, b = 160 ft, and an unknown hypotenuse c. Use the pythagorean theorem to find c.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"a%5E2+%2B+b%5E2+=+c%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28300%29%5E2+%2B+%28160%29%5E2+=+c%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"90000+%2B+25600+=+c%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"115600+=+c%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"c%5E2+=+115600\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"c+=+sqrt%28115600%29\" Apply the square root to both sides\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"c+=+340\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The player ran exactly 340 feet. This is equivalent to 340/3 = 113.333 yards approximately. To convert from feet to yards, you divide by 3.\r
