Answer:
36
Explanation:
- A midsegment of a triangle is a segment that connects the midpoints of two sides of a triangle.
So, FD is a midsegment. (D is a midpoint and so is F)
- A midsegment connecting two sides of a triangle is parallel to the third side and is half as long.
This midsegment connects the two sides EC and AE. The third, remaining, side is AC.
The midsegment is half as long as the third side.
FD = 18.
FD is half of the third side.
FD times 2 = third side.
18 times 2 = 36
The third side, AC, is 35 units long.
