Algebra.Com's Answer #244319 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! If two angles are complementary, they add to 90.\r \n" ); document.write( "\n" ); document.write( "Thus the angles are x and 90-x (that's tricky, reason it out why it is so)... \n" ); document.write( "Then \n" ); document.write( "(90-x) = 21 + 2x \n" ); document.write( "90 - x = 21 + 2x \n" ); document.write( "Now subtract 21 and add x to both sides in two steps... \n" ); document.write( "69 = 3x \n" ); document.write( "x = 23 \n" ); document.write( "90-x = 67 \n" ); document.write( " |
