I am assuming that your right angle is at B
\n" ); document.write( "AB^2 + BC^2 = AC^2
\n" ); document.write( "AB^2 = AC^2 - BC^2
\n" ); document.write( "AB^2 = (8)^2 - (4)^2
\n" ); document.write( "AB^2 = 64 - 16
\n" ); document.write( "AB = square root of 48
\n" ); document.write( "AB = 6.9 ( 1 decimal place)
\n" ); document.write( "
\n" );
