Algebra.Com's Answer #20206 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! The sum of the measures of the angles in any triangle is 180 degrees. In triangle ABC, angle A is five more than twice the measure of angle B. Angle C is five less than three times the measure of angle B. \n" ); document.write( "I tried: 2b+5=A 3B{c-5} \n" ); document.write( "GO STEP BY STEP AND GO SYSTEMATICALLY. \n" ); document.write( "SINCE B HAS COMMON RELATION WITH BOTH A AND C..START WITH THAT \n" ); document.write( "LET ANGLE B =B \n" ); document.write( "LET US FIND A.. \n" ); document.write( "TWICE THIS =2B \n" ); document.write( "5 MORE THAN THIS =2B+5=A\r \n" ); document.write( "\n" ); document.write( "LET US FIND C... \n" ); document.write( "THREE TIMES B..=3B \n" ); document.write( "5 LESS THAN THIS ... \n" ); document.write( "3B-5=C\r \n" ); document.write( "\n" ); document.write( "SO NOW SUM UP THE 3 ANGLES... \n" ); document.write( "A+B+C=2B+5+B+3B-5=180 \n" ); document.write( "6B=180 \n" ); document.write( "B=30 \n" ); document.write( "SO A=2B+5=2*30+5=65 \n" ); document.write( "C=3B-5=3*30-5=85 \n" ); document.write( " |
