Scale factor is defined as
s=size of image / size of preimage.
Here BO is preimage.
B'O'=BO' is image, since the position of B is invariant, so B=B'.
So scale factor = B'O'/BO = 9/27 = 1/3.

Step-by-step explanation:
Answer:
h = 16 feet
Step-by-step explanation:
Pythagoras´ theorem establishes, that in a right triangle square of the hypothenuse (c²) is the sum of leg ( b²) plus leg (a²)
Then
c² = a² + b²
where according to the problem statement
(20)² = h² + (12)² ( h is the height of the flagpole )
h² = 400 - 144
h² = 256
h = √ 256
h = 16 feet
Cool? Is there more to this question or?
