In the diagram, triangle BDF and ACE have the same area. If DB = 2, BA = 4, and AE = 3, find the length of EC.
triangle BDF and ACE have the same area
Except ACE is a straight line. Typo?
.
In the diagram, triangles BDF and FCE have the same area. If DB = 2, BA = 4, and AE = 3, find the length of EC.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If [BDF] = [FCE] then [ABC] = [ADE]
[ADE] = 1/2(6 * 3) = 9
1/2[4 * (3 + EC)] = 9
EC = 1.5
