Can you have a negative reference angle Math Practice

WebLet's suppose that you know a triangle has angles 90 and 50 and you want to know the third angle. Let's call the unknown angle x. x + 90 + 50 = 180 x + 140 = 180 x = 180 - 140 x = 40 As for the side lengths of the triangle, you need more information to figure those out. WebSo, if our given angle is 214°, then its reference angle is 214° – 180° = 34°.

Weba negative 295 degree rotation. Although I would not say a 425 degree angle is "acute," I would say it had an acute "reference angle." The purpose of the language is to help us understand the things which are alike, and those which are different, so to me, it wouldn't be accurate to just say a 425 degree angle is acute.
