The scale factor is 0.25, not 4 in this case. You can determine this by looking at the comparison of the triangles. The first triangle is 4.4 and the second one is 1.1, so the scale factor is determined by looking at what is happening to the first one to result in the second.
0.25 is 1/4. The second hypotenuse is 1/4 the hypotenuse of the first one.
Based from background knowledge, I believe that the correct answer among all of the given choices would be B.) 38/2. This would give you 19. If I am mistaken, please correct me. But I am definitely positive that this is the right answer.
I hope this is the answer you were looking for and that it helps!! :)
