This is a right triangle with a hypotenuse=15, the base=x & the other side=x+3.
\n" ); document.write( "x^2+(x+3)^2=15^2
\n" ); document.write( "x^2+x^2+6x+9=225
\n" ); document.write( "2x^2+6x+9-225=0
\n" ); document.write( "2x^2+6x-216=0
\n" ); document.write( "2(X^2+3X-108)=0
\n" ); document.write( "2(X-9)(X+12)=0
\n" ); document.write( "X-9=0
\n" ); document.write( "X=9 FT. DISTANCE FROM THE WALL AND THE BASE OF THE LADDER.
\n" ); document.write( "9+3=12 FT. DISTANCE OF THE LADDER UP THE WALL.
\n" ); document.write( "
