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 = .

The triangle midsegment theorem says the midsegment of 2 sides of a triangle is parallel to the third side and half as long.

Step-by-step explanation:

see diagram

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 = BA.

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

Now, since BE = x, then BC = 10
