Algebra.Com's Answer #379693 by flame8855(424)![]() ![]() You can put this solution on YOUR website! let a be the length of the hypotenuse \n" ); document.write( "let b & c be the lenth of the other two sides. \n" ); document.write( "a=34 \n" ); document.write( "c^2 + b^2= a^2 \n" ); document.write( "b^2+c^2= 156 \n" ); document.write( "a+b+c=80 \n" ); document.write( "solve the three equations : \n" ); document.write( "b+c= 80-34=46 \n" ); document.write( "c=46-b \n" ); document.write( "b^2 +(46-b)^2=156 \n" ); document.write( "b^2-46b+480=0 \n" ); document.write( "b=16 or b = 30 \n" ); document.write( "for b = 16 \n" ); document.write( "c=80-16-34 = 30 \n" ); document.write( "for b=30 \n" ); document.write( "c=80-30-34=16 \n" ); document.write( "so the length of the two other sides are 16 and 30 \n" ); document.write( " |
