Algebra.Com's Answer #260648 by apachemexican1(64) ![]() You can put this solution on YOUR website! the meausure of an angle is 20 more than 3 times the meausure of its supplement. What is the smaller angle?\r \n" ); document.write( "\n" ); document.write( "the supplementary angles add up to 180 degrees \n" ); document.write( "so the equation will be set up like so \n" ); document.write( "3x+20+x=180 \n" ); document.write( "combine like terms \n" ); document.write( "4x+20=180 \n" ); document.write( "subtract 20 from both sides of the equation \n" ); document.write( "4x+20-20=180-20 \n" ); document.write( "equals \n" ); document.write( "4x=160 \n" ); document.write( "you then divide 4 from both sides of the equation \n" ); document.write( "4x/4=160/4 \n" ); document.write( "solve for x \n" ); document.write( "x=40\r \n" ); document.write( "\n" ); document.write( "so the smaller angle is 40 degrees \n" ); document.write( "if u were lookin for the measure of the bigger angle as well you would just subtract the smaller angle by 180 and then u would have the bigger angle as well \n" ); document.write( " |
