Question

Which is the angle measure represented by 2 rotations counterclockwise?

Answer 1

Answer:

Option D. 720°

Step-by-step explanation:

In every rotation of a circle angle formed at the center is 360°. Therefore, in a clock which is in the form of a circle, angle formed by two rotations at the center will be 360×2 = 720°

Now question is whether the angle is positive or negative?

Angles are always measured counterclockwise, means angles measured counterclockwise are positive and measured clockwise are negative.

Therefore, 2 rotations counterclockwise is equal to 720°.

Option D. 720° is the answer.
