Algebra.Com's Answer #165137 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! two angles are supplementary. One angle has a measure of 5x+40 and the other has a measure of 2x. What is the measure of the smaller angle? \n" ); document.write( "--------------------- \n" ); document.write( "Angles are supplimentary if their sum is 180 degrees. \n" ); document.write( "----------------- \n" ); document.write( "So, 5x+40 + 2x = 180 degrees \n" ); document.write( "7x + 40 = 180 \n" ); document.write( "7x = 140 \n" ); document.write( "x = 20 \n" ); document.write( "---------------- \n" ); document.write( "angle: 2x = 2*20 = 40 degrees \n" ); document.write( "angle: 5x+40 = 5*20+40 = 140 degrees \n" ); document.write( "------------------------------------ \n" ); document.write( "The measure of the smaller angle is 40 degrees. \n" ); document.write( "=========================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
