I think it might be C.
OpenStudy (cgreenwade2000):
Divide 39 by 20. That should give you the conversion rate. Then you can go backwards and use that number, multiply it by 5 to get x. DO you understand how and why? I can explain it further.
OpenStudy (mathstudent55):
Similar polygons have sides whose lengths are in proportion. You can solve for x by writing a simple proportion: 39/20 = x/5 This is basically the same as what @cgreenwade2000 explained.

So it would be C? I divide it and times by 5.
