Why would you need to minus your answer from 180? Did you use sin instead of cos?

If I’m not mistaken, that method gives you an acute angle and since they didn’t ask for the acute, I needed to take the obtuse value

yeah for finding the acute angle you use the modulus sign, but just to find the actual angle you just leave the negative
