Question 3

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

Revolt · Accepted Answer

D; From the markings on the diagram, we can tell E is the midpoint of BC and is the midpoint of AC: D; We can apply the theorem: ED = BA.: triangle midsegment; Substituting in the expressions for the lengths and solving for x, we get x = .: 5; Now, since BE = x, then BC = .: 10
