How would I go about solving for the cos195?

I thought I would subtract 195 from 360 but after that I don't know what to do.

I don't quite understand your question. You are right in assuming that cos195 = cos(360-195).

This also equals -cos(195-180), does this help?

Please could you rephrase what you are trying to find :)

I'm not exactly sure myself. He question simply said:

"Solve for cos195" and I'm sure we have to use something with subtraction and reference numbers.

If I figure it out I'll get back to you.


- Thank You.
