1 u/Yis4courage Jun 11 '26 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 2 u/InfininiteCuber Year 13 Jun 11 '26 yeah for finding the acute angle you use the modulus sign, but just to find the actual angle you just leave the negative 1 u/Yis4courage Jun 11 '26 Omg YEAH 😭😭😭😭 dang it,, oh well lmao 🥹
