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( "
