Look at this website: http://www.mathwarehouse.com/geometry/similar/triangles/side-splitter-theorem.php Tell me if you need more help!=)

lalala · Answer

Would it look like 8/12 = 12/x ? And then solve the proportion from there right?
or does the proportion need to be set up differently?

blazeryder · Answer

Nope, you got it right! Now what would the answer be?

lalala · Answer

x = 18?
