The diagonal of a rectangle is 13 cm. How long
\n" ); document.write( "is its width if its length is 10 cm?
\n" ); document.write( "---------------------
\n" ); document.write( "Draw the picture:
\n" ); document.write( "You have a right triangle with hypotenuse = 13 and one side is 10
\n" ); document.write( "=====
\n" ); document.write( "Equation:
\n" ); document.write( "Let the length be \"x\":
\n" ); document.write( "13^2 = 10^2 + x^2
\n" ); document.write( "-----
\n" ); document.write( "169 = 100 + x^2
\n" ); document.write( "------
\n" ); document.write( "x^2 = 69
\n" ); document.write( "----
\n" ); document.write( "length = sqrt(69)
\n" ); document.write( "=======================
