Algebra.Com's Answer #565058 by algebrahouse.com(1659)![]() ![]() You can put this solution on YOUR website! x = measure of one angle \n" ); document.write( "x = measure of other angle {two angles are equal} \n" ); document.write( "x + 3 = measure of the third angle {third is 3° greater than each of the other two}\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x + x + x + 3 = 180° {angles of a triangle add up to 180} \n" ); document.write( "3x + 3 = 180 {combined like terms} \n" ); document.write( "3x = 177 {subtracted 3 from each side} \n" ); document.write( "x = 59 {divided each side by 3} \n" ); document.write( "x + 3 = 62 {substituted 59, in for x, into x + 3}\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "62° is the measure of the larger angle \n" ); document.write( " For more help from me, visit: www.algebrahouse.com \n" ); document.write( " |
