Algebra.Com's Answer #552753 by LinnW(1048)![]() ![]() You can put this solution on YOUR website! One of the angles is (9x-1) \n" ); document.write( "the other is (3x+7)\r \n" ); document.write( "\n" ); document.write( "(9x-1) + (3x+7) = 90 \n" ); document.write( "12x + 6 = 90 \n" ); document.write( "add -6 to each side \n" ); document.write( "12x = 84 \n" ); document.write( "divide each side by 12 \n" ); document.write( "x = 7 \n" ); document.write( "So the angle that is (9x-1) = (9(7)-1) = 63 - 1 = 62 degrees. \n" ); document.write( "Since the angles are complementary the other angle is 90 - 62 = 28 degrees.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
