1) the area of a right triangle is 44m squared. find the lengths of its legs if one of the legs is 3 m longer than the other
\n" ); document.write( "Let one of the legs be \"x\".
\n" ); document.write( "The other leg is \"x+3\"
\n" ); document.write( "Area = (1/2)x(x+3)=44
\n" ); document.write( "x(x+3)=88
\n" ); document.write( "x^2+3x-88=0
\n" ); document.write( "(x+11)(x-8)=0
\n" ); document.write( "x= -11 or x=8
\n" ); document.write( "--------------------------------\r
\n" ); document.write( "\n" ); document.write( "2) the hypotneuse of a right triangle is 25m long. the length of one leg is 10m less than twice the other. find the length of each leg.\r
\n" ); document.write( "\n" ); document.write( "Let one of the legs be \"x\".
\n" ); document.write( "The other leg is \"2x-10\".
\n" ); document.write( "Use Pythagoras to get:
\n" ); document.write( "x^2+(2x+10)^2 = 25^2
\n" ); document.write( "x^2 + 4x^2+40x+100=625
\n" ); document.write( "6x^2+40x-525=0
\n" ); document.write( "x=[-40+-sqrt(40^2-4*6*-525)/12
\n" ); document.write( "x=[-40+-sqrt(14200)]/12
\n" ); document.write( "x=6.597 (one of the legs)
\n" ); document.write( "2x+10=23.194 (the other leg)
