Answer:
3
Step-by-step explanation:
We are given that line segment EF is dilated (compressed) by a factor of 2/3 to give line segment E'F'. This means that its length has been multiplied by 2/3.
We are also given the length of E'F' as:
Using this information, we can create a proportion to solve for the length of the original line segment EF:
↓ plugging in the given value, E'F' = 2
↓ multiplying both sides by 3/2
