You can put this solution on YOUR website!
In any given problem there's always an \"unknown\"????
\n" ); document.write( "Simply refer this \"unknown\" data to the letter in the equation you're using.
\n" ); document.write( ".
\n" ); document.write( "For instance you're looking for the hypotenuse of a right triangle with 2 other sides given. We all know in solving this we have to use Pythagorean Theorem and as it states there in equation, \"%28hypotenuse%29%5E2+=+%28opposite%29%5E2+%2B+%28adjacent%29%5E2\" right?
\n" ); document.write( "Now usually they assigned \"letters\" in reference to the data given, where we can say,
\n" ); document.write( "hypotenuse= \"c\"
\n" ); document.write( "opposite= \"b\"
\n" ); document.write( "adjacent= \"a\"
\n" ); document.write( "Well since we're looking for the hypotenuse, \"c\" that represent it is the subject of the equation ----> \"c%5E2+=+a%5E2+%2B+b%5E2\"
\n" ); document.write( "If the opposite or adjacent side is unknown, we'll make \"a\" or \"b\" the subject of the equation ----> \"b%5E2+=+c%5E2+-+a%5E2\" or \"a%5E2+=+c%5E2+-+b%5E2\"
\n" ); document.write( "Hope this help.
