An isosceles triangle has a base 10 units long. if the congruent side lengths have measures to the first decimal place, what is the shortest possible length of the sides?
question 7 options:
20.1
5.1
4.9
10.1

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.

Iagree that is the answer to the question
