ℜ0, -180 is the same rotation as

0 to -180 is the same rotation as -180 to -360

Step-by-step explanation:

0 to -180 is clockwise direction. since the rotation is of a total of 180 degrees, which means that from any angle, it has to rotate an extra 180 degree clockwise. Furthermore, another answer could be from 180 to 0, or 90 to -90, etc.

The answer is  0,180

Step-by-step explanation:

Since 0, -180 is the rotation and if you look at the other rotations like 90, 180 the first rotation would be different. so 0, 180 is the same as 0, -180 because they both would be a full rotation of a 180 rotation. The first number "0 ," would have to be the same.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
