A dinner platter the shape of a regular decagon with a area of 161 and a side length of 4.6 what is the hight of each triangle and the area of each triangle

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
