Camden is creating a model of a pyramid. The model created will need to be scaled up from the blueprint. triangle ACB, point D is on segment AC between points A and C, point E is on segment BC between points B and C If segments DE and AB are parallel, which of the following expressions will help Camden determine the length of DC? DC equals EC times AC all over BC DC = EC DC equals EC times AC all over AB DC = AB
