All the angles below are obtuse angles: Which Angle? Remember to look carefully at which angle you are being asked to name. The obtuse angle is the smaller angle. It is more than 90Â° and less than 180Â°.
In general, the cosine of an obtuse angle is the negation of the cosine of its supplement. In this case that means the cosine of angle C, that is to say angle ACB, is the negation of the cosine of angle ACD. Thatâs why the minus sign appears in the last equation.
