The range of cosine is [-1, 1] which is, therefore, the domain of cos-1. As a result, cos-1(2) is not defined.

In order to apply the law of cosines to find the measure of an interior angle it is enough to know which of the follwing?

To apply the law of cosines to find the measure of an interior angle in a triangle, you need to know the lengths of all three sides of the triangle. Specifically, if you have sides ( a ), ( b ), and ( c ), you can find the angle opposite to side ( c ) using the formula ( c^2 = a^2 + b^2 - 2ab \cos(C) ). From this equation, you can isolate ( \cos(C) ) and then use the inverse cosine function to determine the measure of angle ( C ).
