Given:
CDEF is dilated by a scale factor of to form the quadrilateral C'D'E'F'.
To find:
The measure of side E'F'.
Solution:
If a figure is dilated by a scale factor of k, then the side of dilated figure is k times of corresponding side of original figure.
CDEF is dilated by a scale factor of to form the quadrilateral C'D'E'F'. So,
From the given figure it is clear that . So,
Therefore, the measure of side E'F' is 9 units.
Hello!
Answer:
The answer should have positive sign.
Step-by-step explanation:
First, you subtract by 5 from both sides of an equation.
Then, simplify and subtract by the numbers from left to right.
You divide by 6 from both sides of an equation.
Finally, divide numbers from left to right.
, which is our correct answer.
