1. The problem statement, all variables and given/known data 13) An angle has a radian measure of Pi/8 . Find the exact radian measure of a) Its supplement b) Its complement 2. Relevant equations 3. The attempt at a solution I tried converting it to degrees by doing degrees / pi and then doing 90 - that angle i got to give me supplement / compliment, then re convert it back into radiants, However that didnt work. Does anyone know how to solve this?
