The hypotenuse is 30 yd. The missing leg is 18 yd.
The missing leg is 24 yd.
The formula 242 + 02 = = 302 can be used
to find the missing leg measure.
The formula 302 + 2 = 242 can be used
to find the missing leg measure.

The answer is a good luck

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.
