James is building a ramp for his elderly grandmother. If he builds it 3 feet above the ground and if it has a 4 foot base, how long will the ramp be?
\n" ); document.write( "A. 3 feet
\n" ); document.write( "B. 5 feet
\n" ); document.write( "C. 8 feet
\n" ); document.write( "D. 10 feet
\n" ); document.write( ".
\n" ); document.write( "It's a 3-4-5 triangle -- so it would be B.
\n" ); document.write( "Or, you can apply Pythagorean theorem:
\n" ); document.write( "Let r = ramp
\n" ); document.write( "then
\n" ); document.write( "r^2 = 3^2 + 4^2
\n" ); document.write( "r^2 = 9 + 16
\n" ); document.write( "r^2 = 25
\n" ); document.write( "r = 5 feet\r
\n" ); document.write( "\n" ); document.write( "
