Algebra.Com's Answer #195221 by roseo(33) ![]() You can put this solution on YOUR website! Let one side of the triangle be x and then the other leg of the triangle will be x+14. By using the Pythagorean Theorem we would have \n" ); document.write( "x^2+(x+14)^2=26^2 \n" ); document.write( "x^2 +x^2+28x+196 = 676 \n" ); document.write( "By combining like terms and putting everything on one side we have \n" ); document.write( "2x^2+28x-480=0 \n" ); document.write( "To simplify divide both sides by 2 \n" ); document.write( "x^2+14x-240=0 \n" ); document.write( "By factoring we have \n" ); document.write( "(x+24)(x-10)=0 \n" ); document.write( "So the x+24=0 and x-10=0, therefore \n" ); document.write( "x=-24 and x=10, \n" ); document.write( "x=-24 is a nonsense answer be the side of a triangle cannot have a negative measure so one leg of the triangle is 10 and the other would be x+14 or 24. \n" ); document.write( " |
