If you had two or more obtuse angles, their sum would exceed 180 and so they couldn't form a triangle. Well I thought you can use trigonometry or Complete Pythagoras theorem , but I don't really know how to apply it, Let $|AB|=c$, $|BC|=a=c+2$, MTH 165 College Algebra, MTH 175 Precalculus, { "7.1e:_Exercises_-_Law_of_Sines" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.
