Respuesta :

We manipulate the given equation in order to solve for EC. We do this by cross multiplying. 
The resulting equation will be:
EC = (4 x 3)/5
EC = 12/5 = 2.4

Additionally, the side-splitter theorem works for this problem since DE and AC are parallel to each other, therefore splitting the remaining two sides into proportional segments.
