um there is no 60 30 12 triangle since all triangle angles must add up to 180 degrees like a 90 45 45 or a 60 60 60. thats problem number 1, the other problem with this is there is no \"of the following\" so that would be helpful in solving the problem. please make sure the problem is written correctly thanks. \n" ); document.write( "
