The answer is : Both plane A and B.
Answer:
The answer is B.180°.
Step-by-step explanation:
The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.
In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.
Therefore, the only option that applies is B.180°
The last one is the answer.......
First, we divide 54 by 4.5 to find out how many miles she can ride in 1 hour, then multiply that to 6 to find how many miles she can ride in 6 hours. 54 / 4.5 = 12, and 12 x 6 = 72, so she can ride 72 miles in 6 hours. :)
