Circumference has the answer in square units.
360 - (170 + 80)
= 360 - 250
= 110
MAJ = 110/2 = 55
answer
55
Answer:
The length of segment AC is two times the length of segment A'C'
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z ----> the scale factor
A'C' ----> the length of segment A'C'
AC ----> the length of segment AC
so
we have that
---> the dilation is a reduction, because the scale factor is less than 1 and greater than zero
substitute

therefore
The length of segment AC is two times the length of segment A'C'
