Algebra.Com's Answer #192249 by Greenfinch(383)![]() ![]() You can put this solution on YOUR website! If angle A is A \n" ); document.write( "angle B is 4A \n" ); document.write( "angle C is 5A - 9 \n" ); document.write( "Total is 180 \n" ); document.write( "So A + 4A + 5A - 9 = 10A - 9 = 180 \n" ); document.write( "10A = 189 \n" ); document.write( "A = 18.9 \n" ); document.write( "B = 75.6 \n" ); document.write( "C = 85.5 \n" ); document.write( "Total = 180 \n" ); document.write( " |
