Algebra.Com's Answer #521555 by dkppathak(439)![]() ![]() You can put this solution on YOUR website! one leg of of a right triangle is 2 meters longer than the other leg. The hypotenuse is 2 meters less than twice the length of the shorter leg. Find the length of the shorter leg. \n" ); document.write( "Answer \n" ); document.write( "let smaller leg is x meter\r \n" ); document.write( "\n" ); document.write( "length of other leg will be X+2 ( as per given conditions) \n" ); document.write( "length of hypotenuse will be 2x-2(as per given conditions ) \n" ); document.write( "by Pythagoras theorem of right anle triangle \n" ); document.write( "we know \n" ); document.write( " H^2=smaller leg^2+other Leg^2 \n" ); document.write( "(2x-2)^2= X^2+ (X+2)^2 \n" ); document.write( "4x^2+4-8x =x^2+x^2+4+4x \n" ); document.write( "4x^2+4-8x =2x^2+4+4x \n" ); document.write( "4x^2+4-8x - 2x^2 -4-4x = 0 \n" ); document.write( "2x^2-12x=0 \n" ); document.write( "2x(x-6)=0 \n" ); document.write( "therefor \n" ); document.write( "2x=0 or x-6=0 \n" ); document.write( "x=0 or x=6 \n" ); document.write( "neglecting x=0 \n" ); document.write( "therefore x=6 meter \n" ); document.write( "hypotenuse will be 2x-2=2x6-2=10 meter \n" ); document.write( "other leg will be x+2 = 8 meter \n" ); document.write( "Answer \n" ); document.write( "smaller leg =6 meters \n" ); document.write( "other leg =8 meters \n" ); document.write( "hypotenuse =10 meters \r \n" ); document.write( "\n" ); document.write( "A\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
