Question

Help please! Thank you!

Answer 1

The answer would be x = 20. First, you must set up a proportion, since you know that the two polygons are similar: 12/48 • 5/x. Then, you have to do cross multiplication which would result in 12x = 240. Afterwards, you must divide both sides by 12, giving you x = 20.

Answer 2

The correct answer is 20, the other side went from 12-->48 meaning it was a x4 expansion, so the side that was 5 is now 20
