In a right triangle, one leg is twice the other leg, and the area is 9. How long is the hypotenuse?\r
\n" ); document.write( "\n" ); document.write( "Let x = one side, the other side = 2x
\n" ); document.write( ":
\n" ); document.write( "Area of a triangle = (1/2)*b*h; in a right triangle, the base and the height
\n" ); document.write( "are the same as the sides:
\n" ); document.write( ":
\n" ); document.write( "(1/2)*x*2x = 9
\n" ); document.write( "(1/2)*2x^2 = 9
\n" ); document.write( " x^2 = 9
\n" ); document.write( " x = 3
