yet another geometry question
posted by mike on .
Points D, E and F are the midpoints of the sides of triangle ABC. If AD=6, CF=4 and the perimeter of triangle ABC = 30, then find BE.
If D is between A&B, E is between B&C and F is between C&A, then the perimeter is 6+6+4+4 + (twice length of BE)= 30
