Two right triangles are similar. the legs of one of the triangles are 5 and 12. the second right triangle has a hypotenuse with a length of 39. what is the scale factor between the two triangles?

a. 4: 3
b. 1: 3
c. 2: 6
d. 1: 2

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.
