Algebra.Com's Answer #351186 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! Let A = the measure of the first two angles \n" ); document.write( "The 3rd angle will be 180 - A - A = 180 - 2A \n" ); document.write( "Given: sum of the first two is 1/2 the 3rd: \n" ); document.write( "2A = (180 - 2A)/2 \n" ); document.write( "Solve for A: \n" ); document.write( "4A = 180 - 2A \n" ); document.write( "6A = 180 \n" ); document.write( "A = 30 \n" ); document.write( "So the angles are 30, 30 and 120 \n" ); document.write( " |
