Algebra.Com's Answer #648605 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Call the measure of the angle you need, x. \n" ); document.write( "Its complement is 90-x. \n" ); document.write( "Its supplement is 180-x. \n" ); document.write( "Then we write \n" ); document.write( "x + 2(90-x) + 3(180-x) = x + 490 \n" ); document.write( "Now solve for x... \n" ); document.write( "x + 180 - 2x + 540 - 3x = x + 490 \n" ); document.write( "subtract the x, combine the rest... \n" ); document.write( "720 - 5x = 490 \n" ); document.write( "subtract 720 and divide by -5 \n" ); document.write( "-5x = -230 \n" ); document.write( "x = 46 degrees \n" ); document.write( " |
