Generally when speaking about an angle measure using radians, the symbol π is used.( for example, one might say an angle measure was 5π/3 radian). the question for you to answer is this; is 5π/3 radians the same as 5/3 radiams ?

No because 5π/3 is a completely different number than 5/3.

5/3 exists as a radian angle but it is not equal to 5π/3

It ain't coterminal either.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Istg idk..if there all the same length there all the same number but use google
