What does it mean to refer to a 20-in TV set or a 25-in TV set?
\n" ); document.write( "Such units refer to the diagonal of the screen.
\n" ); document.write( "A 10-in TV set also has a width of 8 inches.
\n" ); document.write( "Question:
\n" ); document.write( "What is the height?
\n" ); document.write( "Draw a rectangle that has a width = 8\" and a diagonal = 10\"
\n" ); document.write( "-----
\n" ); document.write( "Let the height be \"x\".
\n" ); document.write( "Use Pythagoras to find \"x\":
\n" ); document.write( "Equation:
\n" ); document.write( "10^2 = x^2 + 8^2
\n" ); document.write( "100 = x^2 + 64
\n" ); document.write( "x^2 = 36
\n" ); document.write( "x = 6\"
\n" ); document.write( "Ans: height = 6\"
