Algebra.Com's Answer #70419 by edjones(8007)![]() ![]() You can put this solution on YOUR website! Let L=largest angle L/2=smallest L-30=middle \n" ); document.write( "L+L/2+(L-30)=180 \n" ); document.write( "multiply 2 times both sides. 2L+L+2L-60=360 \n" ); document.write( "Combine terms and add 60 to both sides. 5L=420 \n" ); document.write( "divide 5 intoboth sides. L=84 L/2=42 L-30=54 \n" ); document.write( "Check: \n" ); document.write( "84+42+54=180 \n" ); document.write( "Ed \n" ); document.write( " |
