Algebra.Com's Answer #499311 by LinnW(1048)![]() ![]() You can put this solution on YOUR website! 2/3 of right angle is 2/3 of 90 or 60 \n" ); document.write( "The remaining two angles total 120 since the sum of the 3 needs to be 180 \n" ); document.write( "Set x = one angle \n" ); document.write( "set (x+18) = the other angle \n" ); document.write( "x + (x+18) = 120 \n" ); document.write( "2x + 18 = 120 \n" ); document.write( "subtract 18 from each side \n" ); document.write( " 2x = 102 \n" ); document.write( " x = 51 \n" ); document.write( " (x+18) = 51+18 = 69 \n" ); document.write( "So the angles are 60 51 and 69 . \n" ); document.write( " |
