i am getting your first answer$$D=x\csc(y°)$$

anonymous · Answer

I was correct the first time?

unklerhaukus · Answer

well i dont understand your notation thin your second answer

unklerhaukus · Answer

what made you change your answer?

unklerhaukus · Answer

$$D=x\csc(y°)$$
i think it is correct

anonymous · Answer

I redid the problem because I erased my previous work and apparently got something different so one of those is wrong for sure.

anonymous · Answer

If youre getting that twice and I got it once its probably that answer then haha. Thanks for the check
