Hello,
\n" ); document.write( "Let's have x represent the length of each side of the triangle. Now we can
\n" ); document.write( "write an equation as using Pythagorean formula:
\n" ); document.write( "x^2+1/2x^2=15^2
\n" ); document.write( "This can be written out as:
\n" ); document.write( "1 1/2 x^2=225
\n" ); document.write( "Divide each side by 1.5 to get:
\n" ); document.write( "x^2=150
\n" ); document.write( "Square root both sides:
\n" ); document.write( "x=sq rt 150 or rewritten as 5 sq rt 6
\n" ); document.write( "Make sense?
