What rotation about the origin is equivalent to R-500°?

The correct answer is R220

Step-by-step explanation:

What rotation about the origin is equivalent to R-500°.

The answer is R220.

If you can add or subtract a multiple of 360° then they are equivalent.

Lets take an example. We will add 720 which is a multiple of 360

-500+720 = 220

You can check the value and see the difference is divisible by 360 or not.

220 - (-500) = 220+500

= 720

which is divisible by 360.

Thus the correct answer is R220 ...
