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.

Answer:
175-119= 56
Step-by-step explanation:
because 68%of 175 = 119
so she has washed 119 and 56 are left
Answer: 7
Step-by-step explanation:
First set up your equation 40+21x=187
Subtract 40 from each side 187-40=147 40-40=0 Bring down your 21x than divide 147 by 21. 147÷21=7
Answer:
sec(B)=b. ab/bc
sin(B)=c. ac/ab
csc(B)=f. ab/ac
cot(B)=a. bc/ac
tan(B)=e. ac/bc
cos(B)=d. bc/ab
