What is the length of BC?

From the markings on the diagram, we can tell E is the midpoint of BC and is the midpoint of AC

We can apply the theorem: ED = BA.

Substituting in the expressions for the lengths and solving for x, we get x = .

Now, since BE = x, then BC = .

Answer:

From the markings on the diagram, we can tell E is the midpoint of BC and D is the midpoint of AC

We can apply the triangle midsegment theorem: ED = [tex]\frac{1}{2 }{[/tex]BA.

Substituting in the expressions for the lengths and solving for x, we get x = 5

Now, since BE = x, then BC = 10
