Algebra.Com's Answer #156313 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let's call the missing angle A. \n" ); document.write( "Then its supplement is 180-A, so... \n" ); document.write( "180-A = 3A+20 \"...the supplement...is 20 degrees more than 3 times the...angle\" \n" ); document.write( "Simplify and solve for A. Subtract 20 from both sides. \n" ); document.write( "160-A = 3A Add A to both sides. \n" ); document.write( "160 = 4A Divide both sides by 4. \n" ); document.write( "40 = A and 180-A = 140 \n" ); document.write( "The two angles are: \n" ); document.write( "40 degrees and 140 degrees. \n" ); document.write( " \n" ); document.write( " |
