The triangle xyz has three sides and three angles
Neither law can be used to solve the triangle
How to determine the appropriate method?
As a general rule, the law of sines states that:
x/sin(X) = y/sin(Y) = z/sin(Z)
As a general rule, the law of cosines states that:
x^2 = y^2 + z^2 - 2yz cos(X)
From the question, we understand that only the angle measures are given.
The sine and the cosine laws above require at least one side length of the triangle in order to solve the triangle
Since the side lengths are not known, then neither of the laws can be used
