Option B: $\frac{AB}{BC}=\frac{AE}{ED}$ is sufficient to prove that $BE$ ll $CD$

Explanation:

Given that ACD is a triangle.

The line EB intersects the sides AC and AD of the triangle.

The point E intersect the side AD and B intersect the side AC.

We need to prove that $BE$ ll $CD$

Then, the side splitter theorem states that "If a line intersects two sides of a triangle and divides the sides proportionally, the line is parallel to the third side of the triangle".

From the side splitter theorem, the line EB intersects the two sides of the triangle AC and AD and divides the sides proportionally.

Thus, the proportion of the sides is given by

$\frac{AB}{BC}=\frac{AE}{ED}$

This proportionality shows that the line is parallel to the third side of the triangle.

Hence, $\frac{AB}{BC}=\frac{AE}{ED}$ is sufficient to prove that $BE$ ll $CD$

Therefore, Option B is the correct answer.

Tcecarenko [31]

Answer:

405 bagels 27 an hour

Step-by-step explanation:

this is because when you divide 270 by 10 you get 27 which is how much per hour then multiply the # of bagels and the # of hours you get is 405. In other words you first want to know how many bagels it took to get to 270 bagels in 10 hours.Hope it helped.
