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
\frac{2.2}{x} = \frac{x}{4.8}
x^{2} =(2.2)(4.8)=10.56
x=3.2   (nearest tenth)

Answer: B. 3.2

This is for leadership

Answer:

I don't think many schools do Powderpuff which is where boys cheer and girls play football. You can do a live Insta and congratulate the students who made the team and mail them gift cards and/or gift baskets. You can also buy basket balls and footballs for each member and decorate it with their names and numbers. I'm also in Student Council so, if you have any other questions feel free to post them!!
