Can what perform algebra?
Answer:
Step-by-step explanation:
Let x = length of segment EF.
Assume that
(a) line segments AD, EF, and BC are parallel, and
(b) the vertical distance between AD and EF is equal to the vertical distance between EF and BC.
Then from similarity between geometric shapes, we can write


x=3.2 (nearest tenth)
Answer: B.
3.2
