Ответ:
C'( 5 , 2 ) .
Step-by-step explanation:
Given : if pentagon ABCDE is rotated 180 degrees around the origin to create pentagon A’B’C’D’E,
To find : what is the ordered pair of point C.
Solution : We have given that
ABCDE is rotated 180 degrees around the origin.
Coordinates of C ( -5 , -2)
By the rotation rule of 180° (x ,y) →→ ( -x , -y) .
Then Coordinates of C ( -5 , -2) →→ C'( 5 , 2 ) .
Therefore, C'( 5 , 2 ) .

Pedometer + math = 0.54 GB. Fits in 0.64 GB.
Photo = 0.403 GB. Fits in 0.64 GB, but only 0.237 GB left.
Not enough for pedometer (0.24)
or math (0.3) .
